Abstract

R1= Rz= COOH) or its corresponding potassium acid salt VJ (111, R1= COOK, Rs= COOH). Pyrolysis of 2-phenylthiazole-4, 5-dicarboxylic acid caused evolution of carbon dioxide and the formation of 2-phenylthiazole-4-carboxylic acid VI1 (111, R1= COOH, R2= H), The salt of this same monobasic acid also resulted from the pyrolysis of the potassium acid salt (VI) of the dibasic acid. The structure of acid VI1 was demonstrated both positively and ...
