✦ Synopsis

The 5-imino-A2-1,3,4_thiadiazolines reported sofar' were prepared from hydrazidic halides and thiourea or KSCN. The preparation of the hydrazidic halides is limited to either the reaction of a hydrazide with PC15 or the halogenation of an aldehydic hydrazone2. In this communication we wish to report an efficient one step synthesis of 2-acetyl-4-aryl-5-imino-A2-1,3,4thiadiazolines (1 a-e) from (2) and aryldiazonium chlorides. No syntheses of
