A copper-catalyzed three-component reaction of triethoxysilanes, sulfur dioxide, and hydrazines

Wang, Xianbo,Xue, Lijun,Wang, Zhiyong

, p. 4056 - 4058 (2014)

A three-component reaction of triethoxysilanes, sulfur dioxide, and hydrazines catalyzed by copper(II) acetate is reported, leading to N-aminosulfonamides in good yields. Not only triethoxy(aryl)silanes but also triethoxy(alkyl)silanes are compatible during the process of insertion of sulfur dioxide. Additionally, diethoxydiarylsilanes are suitable under the conditions as well.
