Dirhodium(II)-Catalyzed Synthesis of N-(Arylsulfonyl)hydrazines by N–H Amination of Aliphatic Amines

Abstract

AbstractThis study reports the development of Rh(II)-catalyzed N–N bond-forming reaction of amino acid derivatives or aliphatic amines to provide hydrazine derivatives through the combined use of Rh2(esp)2 and [(3,4-dimethoxyphenyl)sulfonylimino]-2,4,6-trimethylphenyliodinane (3,4-(MeO)2C6H3SO2N=IMes). This is the first report of N–H amination of aliphatic amines with metal–nitrene species.
