摘要：

1,2,4-Triazolo[4,3-a]pyrimidines, thiadiazolines, selenadiazolines, and unsymmetrical azines were synthesized via reactions of a 4-isopropylbenzoyl bromide 4-nitrophenylhydrazone with each of potassium thiocyanate, potassium selenocyanate, ethyl 6-methyl-4-[4-(methylethyl)phenyl]-2-methylthio-3,4-dihydropyrimidine-5-carboxylate, and alkyl carbodithioate.
