Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). Ethyl formate has the characteristic smell of rum and is partially responsible for the flavor of raspberries , [ 3 ] occurring naturally in some plant oils, fruits, and juices.
Formate is a common C-1 source in living systems. It is formed from many precursors including choline, serine, and sarcosine. It provides a C-1 source in the biosynthesis of some nucleic acids. Formate (or formic acid) is invoked as a leaving group in the demethylation of some sterols. [2] These conversions are catalyzed by aromatase enzymes ...
Formic acid (from Latin formica ' ant '), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH and structure H−C (=O)−O−H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. Esters, salts and the anion derived from formic acid are ...
Infobox references. Methyl formate, also called methyl methanoate, is the methyl ester of formic acid. The simplest example of a carboxylate ester, it is a colorless liquid with an ethereal odour, high vapor pressure, and low surface tension. It is a precursor to many other compounds of commercial interest. [4]
Triethyl orthoformate (TEOF) is an excellent reagent for converting compatible carboxylic acids to ethyl esters. Such carboxylic acids, refluxed neat in excess TEOF until low-boilers cease evolution, are quantitatively converted to the ethyl esters, without need for extraneous catalysis. [5]
Ortho esters are readily hydrolyzed in mild aqueous acid to form esters: . RC(OR′) 3 + H 2 O → RCO 2 R′ + 2 R′OH For example, trimethyl orthoformate CH(OCH 3) 3 may be hydrolyzed (under acidic conditions) to methyl formate and methanol; [5] and may be further hydrolyzed (under alkaline conditions) to salts of formic acid and methanol.
Ethyl chloroformate is an organic compound with the chemical formula ClCO2CH2CH3. It is the ethyl ester of chloroformic acid. It is a colorless, corrosive and highly toxic liquid. It is a reagent used in organic synthesis for the introduction of the ethyl carbamate protecting group [ 3 ] and for the formation of carboxylic anhydrides.
Butyl group. In organic chemistry, butyl is a four- carbon alkyl radical or substituent group with general chemical formula −C4H9, derived from either of the two isomers (n -butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups: The second isomer of butane, isobutane, can also ...
