A palladium-catalyzed coupling reaction of aryl nonaflates, sulfur dioxide, and hydrazines

A facile route to synthesise N-aminosulfonamides through a palladium-catalyzed coupling reaction of aryl nonaflates, sulfur dioxide, and hydrazines is reported. This transformation proceeds in the presence of Pd(OAc)2/XantPhos, and TBAB in 1,4-dioxane at 80°C, leading to the corresponding N-aminosulfonamides in moderate to good yields. The reaction scope has been demonstrated, and good functional tolerance is observed. A plausible mechanism is proposed through the insertion of sulfur dioxide.

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

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.

Metal-free aminosulfonylation of aryldiazonium tetrafluoroborates with DABCO×(SO2)2 and hydrazines

The coupling of aryldiazonium tetrafluoroborates, DABCO×(SO 2)2, and hydrazines under metal-free conditions leads to the formation of aryl N-aminosulfonamides. The reaction proceeds smoothly at room temperature and shows broad functional-group tolerance. A radical process is proposed for this transformation. The coupling of aryldiazonium tetrafluoroborates, DABCO×(SO2)2, and hydrazines under metal-free conditions leads to the formation of aryl N-aminosulfonamides. The reaction proceeds under mild reaction conditions, is fast, has a broad substrate scope, and gives the products in high yiels (21 examples). A plausible mechanism that involves a radical process is also proposed. Copyright
