Data concerning the initial steps in the reductive condensation of trichloromethylarenes with hydroxylamine or hydrazines in pyridine have been obtained.High yields of the products of the reductive condensation obtained even at equimolar ratios of trichloromethylarene with hydroxylamine or hydrazine as well as the formation of unusual products, i.e., 4-pyridylhydrazones of substituted benzaldehydes, have been interpreted as the results of the participation of pyridine in the reaction as a reductive agent. - Key words: trichloromethylarenes, reductive condensation with hydroxylamine or hydrazines, role of pyridine; 4-pyridylhydrazones of substituted benhaldehydes.
