Prepn. of bactericidal nitro aldimine(s) - by treating a nitro aldehyde with an amine and a basic ion exchange resin

摘要

Nitro aldimines of formula (I) X=O or S R=alkyl, (opt. substd. by cycloalkyl, aryl or heterocycle), cycloalkyl (opt. substd. by one or more alkyl gps.), aryl or dialkylamino; are prepd. by treating a nitroaldehyde (II) with a prim. amine (III), this reaction being effected in the presence of a strong basic ion exchange resin.
