摘要：
PURPOSE:To simply and rapidly produce various sulfenamide derivatives in good yield by treating an amide type compound with sodium hydride and then reacting the resultant compound with a disulfide derivative. CONSTITUTION:An amide type compound (e.g. 2-thiophenecarboxyamide) expressed by formula I (R is H, aryl, heterocyclic ring, alkyl, dialkylamino or alkoxy) is treated with sodium hydride and then reacted with a disulfide derivative (e.g. tetraethylthiuram disulfide) expressed by formula II (R is N,N- disubstituted thiocarbamoyl, aroyl, aryl or heterocyclic ring) to afford a sulfenamide derivative [e.g. N-(2-thenoyl)-S-diethylthiocarbamoylsulfenamide] expressed by formula III. Raw materials for the aforementioned method are readily available and reagents are inexpensive. The product has silver halide photographic inhibitory effects on fog.
