Abstract
The condensation of 2-amino-1,3,4-thiadiazole perchlorates with β-chlorovinyl ketones, β-chlorovinyl aldehydes, and 1,1,3,3-tetraethoxypropane has given 1,3,4-thiadiazolo [3,2-a]pyrimidinium salts. The structure of the reaction products and the ratio of the isomers formed has been established by PMR spectroscopy.
