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

Abstract A procedure for the synthesis of N-alkyl-, N-cycloalkyl-, N,N-dialkyl-, and N-arylarenesulfinamides from the corresponding sulfenamides using KF/m–chloroperoxybenzoic acid (CPBA) in CH3CN-H2O is described. High efficiency (fast reactions, ease of manipulation, and good yields) and absence of overoxidation are the major advantageous features of this protocol. GRAPHICAL ABSTRACT
