A three-component reaction of triethoxysilanes, sulfurdioxide, 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 sulfurdioxide. Additionally, diethoxydiarylsilanes are suitable under the conditions as well.
