unsymmetrical disulfides (4) and sulfenamides (5). Reactions of 3 with a variety of aromatic thiols at room temperature were generally complete within 5 min and gave unsymmetrical diaryl disulfides in high yields. Aralkyl disulfides were isolated in high yields from the reaction of 3 with aliphatic thiols. The nucleophilic substitution reactions of 3 with amines proceeded smoothly and provided N-substituted
N-三氟乙酰基芳烃亚磺酰胺(3)是合成不对称二硫化物(4)和亚磺酰胺(5)的有效前体。的反应3与多种在室温下芳族硫醇的是在5分钟内完成通常和以高收率得到二芳基不对称二硫化物。从3与脂族硫醇的反应中高收率分离出芳烷基二硫化物。3与胺的亲核取代反应进展顺利,并以良好至极好的收率提供了N-取代的次磺酰胺。
