摘要

A series of secondary N-1-(2-chloroalkylidene) amines has been prepared by condensation of disubstituted acetaldehydes with primary amines followed by chlorination with N- chlorosuccinimide in carbontetrachloride. A study of the reactivity of these N-homologues of α-chloroaldehydes is described. Treatment of the title compounds with sodium methoxide in methanol gave high yields of α, β-unsaturated aldimines. However, N-1-(2-chloro-2- ...
