Cross-coupling reactionsofacyl chlorides,thiol esters, orcarboxylic anhydridesgiveketones. The reaction of acid chlorides in aqueous bases suffered from competitivehydrolysis,911,912but such decomposition was minimized when arylboronic esters and K3PO4·nH2O (n=1.5, 1.5equiv.) were used in toluene at...
155 Pd-catalyzed cyclization afforded the targeted derivatives from condensation of acyl chlorides with primary amines (Scheme 133). Sign in to download full-size image Scheme 133. For medicinal chemistry purposes the thiol group was introduced at C-2 by reacting 4-amino-3-mesitylaminopyridine ...
The most reactive of the carboxylic acid derivatives are the acyl chlorides because the leaving group is a chloride ion, which is a very weak base (Kb Ϸ 10Ϫ20). O CH3CCl ϩ CH3OH O CH3COCH3 ϩ ClϪ Esters are less reactive because the leaving group is an alcohol, which is...
Acid chloride is an organic compound that is composed of a chlorine atom attached to an acyl group. Acid chlorides are also known as acetyl chlorides or acyl chlorides and belong to a larger family of organic compounds calledacyl halides. Acyl halides can be explained as organic compounds that...
