Synthesis and study of novel 1,2,4-triazolylacetic acid derivatives

A range of 1,2,4-triazolylacetic acids and their derivatives with various substituents at the triazole ring position 3 have been synthesized. The properties of the obtained compounds were studied, showing that: 1) triazolylacetic esters are strong acylating agents; 2) all the obtained triazolylacetic acids underwent decarboxylation when heated to the melting point; 3) the CH2 group in the acetyl moiety can react as methylene component in condensation reactions.
