Study of hydrazinolysis of methyl-3-(4-allyl-3-substituted-5-thioxo-4,5-dihydro-1h-1,2,4-triazol-1-yl)propanoates Chemistry

Abstract

By hydrazinolysis of the methyl esters of 3-(4-allyl-3-substituted-5-thioxo- -4,5-dihydro-1H-1,2,4-triazol-1-yl)propanoic acids it was established that depending on the reaction conditions (solvent, additive, temperature, time, etc.) as the end product hydrazide with both an allyl and propyl group can be obtained. It is also shown that the allyl group contained in hydrazides can be selectively reduced by hydrazine hydrate in the presence of air.
