Condensation of salts of 2-amino-1,3,4-thiadiazoles with unsymmetrical β-diketones

  • 27 Accesses

Abstract

The condensation of acetyl ketones with salts of 2-amino-1,3,4-thiadiazoles generally leads to a mixture of isomeric 1,3,4-thiadiazolo[3,2-a]pyrimidinium salts. The structures of the condensation products and the isomer ratios were determined by means of the PMR spectra.
