Abstract

A series of novel substituted 1,3,4-oxa(thia)diazoles and triazoline-3-thiones has been synthesized from thiosemicarbazides and nitriles of arylthio-, arylsulfonylacetic and -propionic acids. A mechanism is proposed for the preparation of 2-amino-5-substituted 1,3,4-thiadiazoles from carboxylic acids in polyphosphoric acid medium.
