| —— | Benzaldehyd-(4-p-chlor-phenyl-selenosemicarbazon) | 14223-65-5 | C14H12ClN3Se | 336.682 | 
A one-pot reaction of arylisoselenocyanates, hydrazine and bis(trichloromethyl) carbonate, in the presence of a base provides an efficient route for the synthesis of 5-arylamino-1,3,4-selenadiazol-2(3H)-ones in good to excellent yields. A plausible mechanism is proposed for the reaction.
