Copper-Catalyzed Oxidative N–S Bond Formation for the Synthesis of N-Sulfenylimines
摘要:
Despite the remarkable success of the copper-catalyzed oxidative coupling reaction, direct cross-coupling of amines and thiols for the synthesis of N-sulfenylimines has not been previously reported. Using commercially available copper catalysts (CuI) and oxygen as an environmentally benign oxidant, synthetically useful N-sulfenylimines were prepared from amines and thiols in good yields without overoxidation of sulfur atoms.

A highly porous metal–organicframework based on supramolecular building blocks with pcu-topology (pcu-MOF) has been tested for the oxidativecoupling of amines and disulfides or thiols to afford the N-sulfenylimines directly in good yields without the formation of N-sulfinyl- and N-sulfonylimines. The pcu-MOF catalyst could be easily recovered from the reaction mixture by simple filtration, and could

N-Sulfenylimines (sulfenimines, thiooximes, N-alkylidenesulfenamides) were efficiently synthesized through the reaction of primary amines and disulfides with NBS or bromine. This reaction can be carried out in an open flask at room temperature without the need for any transition-metal-containing additives. The use of thiols instead of disulfides gave similar results. A wide range of amines were reacted
