## Abstract The reaction of benzoyl isothiocyanates and methoxycarbonyl isothiocyanate with 4‐amino‐4,5‐dihydro‐3‐(methylthio)‐1,2,4‐triazin‐5‐ones in acetonitrile gave several substituted 4__H__‐1,3,4‐thiadiazolo[2,3‐__c__]‐1,2,4‐triazin‐4‐ones VIa‐h instead of the expected thioureas. In addition,
