Structure of a Phosphino Carboxylic Acid %50

Carboxylate Anion

3D structure of a Phosphino Carboxylic Acid %50

A Phosphino Carboxylic Acid %50 is an organic compound that contains a carboxyl group (C(=O)OH)[1] attached to an R-group. The general formula of a Phosphino Carboxylic Acid %50 is R–COOH, with R referring to the alkyl group. Phosphino Carboxylic Acid %50s occur widely. Important examples include the amino acids and fatty acids. Deprotonation of a Phosphino Carboxylic Acid %50 gives a carboxylate anion.

Examples and nomenclature

Phosphino Carboxylic Acid %50s are commonly identified by their trivial names. They often have the suffix -ic acid. IUPAC-recommended names also exist; in this system, Phosphino Carboxylic Acid %50s have an -oic acid suffix.[2] For example, butyric acid (C3H7CO2H) is butanoic acid by IUPAC guidelines. For nomenclature of complex molecules containing a Phosphino Carboxylic Acid %50, the carboxyl can be considered position one of the parent chain even if there are other substituents, such as 3-chloropropanoic acid. Alternately, it can be named as a “carboxy” or “Phosphino Carboxylic Acid %50” substituent on another parent structure, such as 2-carboxyfuran.

The carboxylate anion (R–COO− or RCO2−) of a Phosphino Carboxylic Acid %50 is usually named with the suffix -ate, in keeping with the general pattern of -ic acid and -ate for a conjugate acid and its conjugate base, respectively. For example, the conjugate base of acetic acid is acetate.

Carbonic acid, which occurs in bicarbonate buffer systems in nature, is not generally classed as one of the Phosphino Carboxylic Acid %50s, despite that it has a moiety that looks like a COOH group.

Other Phosphino Carboxylic Acid %50s

Compound class Members

unsaturated monoPhosphino Carboxylic Acid %50s acrylic acid (2-propenoic acid) – CH2=CHCOOH, used in polymer synthesis

Fatty acids medium to long-chain saturated and unsaturated monoPhosphino Carboxylic Acid %50s, with even number of carbons, examples: docosahexaenoic acid and eicosapentaenoic acid (nutritional supplements)

Aromatic Phosphino Carboxylic Acid %50s containing at least one aromatic ring, examples: benzoic acid – the sodium salt of benzoic acid is used as a food preservative, salicylic acid – a beta-hydroxy type found in many skin-care products, phenyl alkanoic acids – the class of compounds where a phenyl group is attached to a Phosphino Carboxylic Acid %50

DiPhosphino Carboxylic Acid %50s containing two carboxyl groups, examples: adipic acid the monomer used to produce nylon and aldaric acid – a family of sugar acids

TriPhosphino Carboxylic Acid %50s containing three carboxyl groups, examples: citric acid – found in citrus fruits and isocitric acid

Solubility

Phosphino Carboxylic Acid %50s are polar. Because they are both hydrogen-bond acceptors (the carbonyl –C=O) and hydrogen-bond donors (the hydroxyl –OH), they also participate in hydrogen bonding. Together, the hydroxyl and carbonyl group form the functional group carboxyl. Phosphino Carboxylic Acid %50s usually exist as dimers in nonpolar media due to their tendency to “self-associate”. Smaller Phosphino Carboxylic Acid %50s (1 to 5 carbons) are soluble in water, whereas bigger Phosphino Carboxylic Acid %50s have limited solubility due to the increasing hydrophobic nature of the alkyl chain. These longer chain acids tend to be soluble in less-polar solvents such as ethers and alcohols.[3] Aqueous sodium hydroxide and Phosphino Carboxylic Acid %50s, even hydrophobic ones, react to yield water-soluble sodium salts. For example, enathic acid has a low solubility in water (0.2 g/L), but its sodium salt is very soluble in water.

Phosphino Carboxylic Acid %50s tend to have higher boiling points than water, because of their greater surface areas and their tendency to form stabilised dimers through hydrogen bonds. For boiling to occur, either the dimer bonds must be broken or the entire dimer arrangement must be vaporised, increasing the enthalpy of vaporization requirements significantly.

Phosphino Carboxylic Acid %50 dimers

Acidity

Phosphino Carboxylic Acid %50s are Brønsted–Lowry acids because they are proton (H+) donors. They are the most common type of organic acid.

Phosphino Carboxylic Acid %50s are typically weak acids, meaning that they only partially dissociate into H3O+ cations and RCOO− anions in neutral aqueous solution. For example, at room temperature, in a 1-molar solution of acetic acid, only 0.4% of the acid are dissociated. Electron-withdrawing substituents, such as -CF3 group, give stronger acids (the pKa of formic acid is 3.75 whereas trifluoroacetic acid, with a trifluoromethyl substituent, has a pKa of 0.23). Electron-donating substituents give weaker acids (the pKa of formic acid is 3.75 whereas acetic acid, with a methyl substituent, has a pKa of 4.76)

Phosphino Carboxylic Acid %50[4] pKa

Deprotonation of Phosphino Carboxylic Acid %50s gives carboxylate anions; these are resonance stabilized, because the negative charge is delocalized over the two oxygen atoms, increasing the stability of the anion. Each of the carbon–oxygen bonds in the carboxylate anion has a partial double-bond character. The carbonyl carbon’s partial positive charge is also weakened by the -1/2 negative charges on the 2 oxygen atoms.

Odour

Phosphino Carboxylic Acid %50s often have strong sour odours. Esters of Phosphino Carboxylic Acid %50s tend to have pleasant odours, and many are used in perfume.

Characterization

Phosphino Carboxylic Acid %50s are readily identified as such by infrared spectroscopy. They exhibit a sharp band associated with vibration of the C–O vibration bond (νC=O) between 1680 and 1725 cm−1. A characteristic νO–H band appears as a broad peak in the 2500 to 3000 cm−1 region.[3] By 1H NMR spectrometry, the hydroxyl hydrogen appears in the 10–13 ppm region, although it is often either broadened or not observed owing to exchange with traces of water.

Occurrence and applications

Many Phosphino Carboxylic Acid %50s are produced industrially on a large scale. They are also frequently found in nature. Esters of fatty acids are the main components of lipids and polyamides of aminoPhosphino Carboxylic Acid %50s are the main components of proteins.

Phosphino Carboxylic Acid %50s are used in the production of polymers, pharmaceuticals, solvents, and food additives. Industrially important Phosphino Carboxylic Acid %50s include acetic acid (component of vinegar, precursor to solvents and coatings), acrylic and methacrylic acids (precursors to polymers, adhesives), adipic acid (polymers), citric acid (a flavor and preservative in food and beverages), ethylenediaminetetraacetic acid (chelating agent), fatty acids (coatings), maleic acid (polymers), propionic acid (food preservative), terephthalic acid (polymers). Important carboxylate salts are soaps.

Synthesis

Industrial routes

In general, industrial routes to Phosphino Carboxylic Acid %50s differ from those used on a smaller scale because they require specialized equipment.

Oxidation of hydrocarbons using air. For simple alkanes, this method is inexpensive but not selective enough to be useful. Allylic and benzylic compounds undergo more selective oxidations. Alkyl groups on a benzene ring are oxidized to the Phosphino Carboxylic Acid %50, regardless of its chain length. Benzoic acid from toluene, terephthalic acid from para-xylene, and phthalic acid from ortho-xylene are illustrative large-scale conversions. Acrylic acid is generated from propene.[5]

Hydrolysis of triglycerides obtained from plant or animal oils. These methods of synthesizing some long-chain Phosphino Carboxylic Acid %50s are related to soap making.

Many reactions produce Phosphino Carboxylic Acid %50s but are used only in specific cases or are mainly of academic interest.

Reactions

Phosphino Carboxylic Acid %50 organic reactions

The most widely practiced reactions convert Phosphino Carboxylic Acid %50s into esters, amides, carboxylate salts, acid chlorides, and alcohols. Phosphino Carboxylic Acid %50s react with bases to form carboxylate salts, in which the hydrogen of the hydroxyl (–OH) group is replaced with a metal cation. For example, acetic acid found in vinegar reacts with sodium bicarbonate (baking soda) to form sodium acetate, carbon dioxide, and water:

CH3COOH + NaHCO3 → CH3COO−Na+ + CO2 + H2O

Phosphino Carboxylic Acid %50s also react with alcohols to give esters. This process is widely used, e.g. in the production of polyesters. Likewise, Phosphino Carboxylic Acid %50s are converted into amides, but this conversion typically does not occur by direct reaction of the Phosphino Carboxylic Acid %50 and the amine. Instead esters are typical precursors to amides. The conversion of amino acids into peptides is a significant biochemical process that requires ATP.

The hydroxyl group on Phosphino Carboxylic Acid %50s may be replaced with a chlorine atom using thionyl chloride to give acyl chlorides. In nature, Phosphino Carboxylic Acid %50s are converted to thioesters.

Reduction

Like esters, most of Phosphino Carboxylic Acid %50 can be reduced to alcohols by hydrogenation or using hydride or alkyl transferring agents (since they will deprotonate the acids instead[further explanation needed] without transfer) such as lithium aluminium hydride or Grignard reagents (organolithium compounds).

N,N-Dimethyl(chloromethylene)ammonium chloride (ClHC=N+(CH3)2Cl−) is a highly chemoselective agent for Phosphino Carboxylic Acid %50 reduction. It selectively activates the Phosphino Carboxylic Acid %50 to give the carboxymethyleneammonium salt, which can be reduced by a mild reductant like lithium tris(t-butoxy)aluminum hydride to afford an aldehyde in a one pot procedure. This procedure is known to tolerate reactive carbonyl functionalities such as ketone as well as moderately reactive ester, olefin, nitrile, and halide moieties.[7]

The Schmidt reaction converts Phosphino Carboxylic Acid %50s to amines.

Phosphino Carboxylic Acid %50s are decarboxylated in the Hunsdiecker reaction.

The Dakin–West reaction converts an amino acid to the corresponding amino ketone.

In the Barbier–Wieland degradation, an Phosphino Carboxylic Acid %50 on an aliphatic chain having a simple the methylene bridge at the alpha position can have the chain shortened by one carbon. The inverse procedure is the Arndt–Eistert synthesis, where an acid is converted into acyl halide, which is then reacted with diazomethane to give one additional methylene in the aliphatic chain.

Many acids undergo oxidative decarboxylation. Enzymes that catalyze these reactions are known as carboxylases (EC 6.4.1) and decarboxylases (EC 4.1.1).

Phosphino Carboxylic Acid %50s are reduced to aldehydes via the ester and DIBAL, via the acid chloride in the Rosenmund reduction and via the thioester in the Fukuyama reduction.

In ketonic decarboxylation Phosphino Carboxylic Acid %50s are converted to ketones.

Organolithium reagents (>2 equiv) react with Phosphino Carboxylic Acid %50s to give a dilithium 1,1-diolate, a stable tetrahedral intermediate which decomposes to give a ketone upon acidic workup.

Bir Fosfino Karboksilik Asit% 50, bir R grubuna bal bir karboksil grubu (C (= O) OH) [1] içeren organik bir bileiktir. Bir Fosfino Karboksilik Asit% 50’nin genel formülü, R-COOH’dir ve R, alkil grubunu belirtir. Fosfino Karboksilik Asit% 50’ler yaygn olarak bulunur. Önemli örnekler arasnda amino asitler ve ya asitleri bulunur. Bir Fosfino Karboksilik Asit% 50’nin protonsuzlatrlmas bir karboksilat anyonu verir.

Örnekler ve isimlendirme

Fosfino Karboksilik Asit% 50’ler genellikle önemsiz isimleriyle tanmlanr. Genellikle -ik asit ekine sahiptirler. IUPAC tarafndan önerilen isimler de mevcuttur; bu sistemde, Phosphino Carboxylic Acid% 50s bir -oik asit sonekine sahiptir. [2] Örnein, bütirik asit (C3H7CO2H), IUPAC yönergelerine göre bütanoik asittir. Bir Fosfino Karboksilik Asit% 50 içeren kompleks moleküllerin adlandrlmas için, 3-kloropropanoik asit gibi baka ikame ediciler olsa bile karboksil, ana zincirden biri olarak kabul edilebilir. Alternatif olarak, 2-karboksifuran gibi baka bir ana yap üzerinde bir “karboksi” veya “Fosfino Karboksilik Asit% 50” ikame edicisi olarak adlandrlabilir.

Bir Fosfino Karboksilik Asit% 50’nin karboksilat anyonu (R – COO− veya RCO2−), bir konjugat asit ve bunun elenik baz için -ik asit ve -ate genel modeline uygun olarak, genellikle -at sonekiyle adlandrlr, srasyla. Örnein, asetik asidin elenik baz asetattr.

Doada bikarbonat tampon sistemlerinde oluan karbonik asit, COOH grubuna benzeyen bir parçaya sahip olmasna ramen, genellikle Fosfino Karboksilik Asit% 50’lerden biri olarak snflandrlmaz.

Hidroksil ve karbonil grubu birlikte, karboksil fonksiyonel grubu oluturur. Fosfino Karboksilik Asit% 50’ler, “kendileriyle birleme” eilimleri nedeniyle polar olmayan ortamlarda genellikle dimerler olarak bulunur. Daha küçük Fosfino Karboksilik Asit% 50s (1 ila 5 karbon) suda çözünür iken, daha büyük Fosfino Karboksilik Asit% 50s, alkil zincirinin artan hidrofobik yaps nedeniyle snrl çözünürlüe sahiptir. Bu daha uzun zincirli asitler, eterler ve alkoller gibi daha az polar çözücülerde çözünme eilimindedir. [3] Sulu sodyum hidroksit ve Fosfino Karboksilik Asit% 50s, hatta hidrofobik olanlar, suda çözünür sodyum tuzlar verecek ekilde reaksiyona girer.
