Abstract
This paper deals with the preparation of a variously substituted non-symmetrical azine set. The starting molecule for their preparation was a protected hydrazone. The protection was performed applying Zwierzak’s method. This procedure is based on the transfer of hydrazine to diethylhydrazidophosphate, which reacts with aldehydes to produce protected hydrazones. In the second step of the procedure, under the action of sodium hydride, the addition of another aldehyde affords non-symmetrical azines in the reaction with the protected hydrazine. The procedure was shown to be a useful and effective method. In this, the second part of our study, we present results devoted to the preparation and full identification of non-symmetrical azines.
