DESCRIPTION AND APPLICATIONS |
|||
|
Acyl is a radical formed from an organic acid by removal of a hydroxyl group.
The general formula of acyl compound is RCO-. Acyl halide is one of a large group of organic
substances containing the halocarbonyl group, have the general formula RCO·X,
where X is a halogen atom
(fluorine, chlorine, bromine, iodine, and astatine) and R may be aliphatic, alicyclic, aromatic,
and H etc. In substitutive chemical nomenclature, their names are
formed by adding '-oyl' as a suffix to the name of the parent compound; ethanoyl
chloride, CH3COCl, is an example. The terms acyl and aroyl halides refer to aliphatic or aromatic derivatives,
respectively. Acyl halides are made by replacing the -OH
group in carboxylic acids by halogen using halogenating agents. They react
readily with water, alcohols, and amines and are widely used in organic
synthetic process whereby the acyl group is incorporated into the target
molecules by substitution of addition-elimination sequence called acylation
reaction. Acylation reaction involves substitution by an electron donor
(nucleophile) at the electrophilic carbonyl group (C=O). Common nucleophiles in the acylation reaction are aliphatic and
aromatic alcohols, both of which give rise to esters and
amines (RNH2)
which give amides. The carboxylic acid (X = OH) itself can
function as an acylating agent when it is protonated by a strong acid catalyst
as in the direct esterification of an alcohol. Two common acylation agents, with
the general formula RCOX, are acid halides (X = halogen atom) and anhydrides (X
= OCOR). Schotten-Baumann reaction is an acylation reaction that uses an acid chloride in
the presence of dilute alkali to acylate the hydroxyl and amino group of organic
compounds. There are also other acylating agents. Stearoyl chloride,
C1-8 fatty acyl halide,
is a yellowish liquid; melts at 20 C. It reacts with water;
soluble in common aprotic organic solvents. It is used
in the synthesis of fine chemicals,
agrochemicals and pharmaceuticals. It is also used as an intermediate for dyes, textile
auxiliaries.
