2.1. Chemistry
In a sodium acetate buffered solution of ethanol 2- and 4-
cyanomethylpyridine (1) and (3) reacts with diazotized aryl amines to form the corresponding (Z)-N-arylpicolinohydrazonyl cyanide
(2) and its isonicotino-hydrazonyl derivatives 4 in overall good
yields (Fig. 1). However, no details of the dyeing behavior or their
antimicrobial activity are reported
