PROCEDEU PENTRU COMPENSAREA UNOR AMIDE

摘要

N,N-disubstituted carboxylic amides having the general formula: (III) in which R1 and R2 each represents an optionally substituted aliphatic hydrocarbyl group or together with the adjacent nitrogen atom represent a heterocyclic group optionally containing one of more further hetero atoms, and R3 is an optionally substituted aliphatic, aromatic, araliphatic or cycloaliphatic group or saturated or aromatic heterocyclic group, are prepared by reacting a compound of the general formula: (IV) with an adduct of the formula: (R1R2N - CHO - X)+C1- (I) or (R1R2N = CHC1)+C1- (II) wherein X is a group selected from -SOC1, -POC12, -PC14, -PC12, -CO-CO-C1 and-CO-C1. The proccss operates with improved yield to give the amides III which are useful as herbicides, insecticides and in the dyestuff industry.
