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

The reactivity of thiosulfonates with nucleophilic reagents was investigated. When reactions of thiosulfonates with thiols were performed, unsymmetricaldisulfides were obtained in excellent yields. This procedure could employ numerous aryl or alkyl thiols. On the other hand, reactions of thiosulfonates with amines proceeded in the presence of a copper catalyst. The procedure was performed efficiently
