Abstract

Hydrazinecarboxylates have been synthesized by reacting substituted acetophenones with carbethoxyhydrazine. One of product is formed as a mixture of E- and Z-isomers. In the process of measuring the melting point of the resulting hydrazinecarboxylates, a transition of one crystalline form to another has been detected. That process has been recorded on video in “time-laps” mode for one of the substances.
