| Abstract: | 1,2,4‐Triazolo4,3‐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. © 2003 Wiley Periodicals, Inc.
