Electroreduction of a series of 2-benzoylamino-5-(1-cyano-2-arylvinyl)-1,3,4-thiadiazoles

Abstract

The electrochemical reduction of a series of 1,3,4-thiadiazoles in alcoholic buffered media has been investigated. The mechanism of the electrode processes is suggested and discussed. A cyclopentene carboxylic acid product is formed through a Ziegler–Throp reaction; the thiadiazole ring is inactive. Confirmation of the mechanism via c.p.e., spectrophotometric analyses, and the study of Hammett's relations is presented.
