simple, practical, and metal‐free protocol has been developed for the synthesis of sulfonamides from sodiumsulfinates and various amines through an iodine‐mediated SN bond formation reaction at room temperature. This green reaction is cost‐effective, operationally straightforward, and especially proceeds under very mildconditions to afford the target products in good to excellent yields (up to 98%)

A nickel-catalyzed product-controllable imidation and amidation of sp3 C–H bonds in substituted toluenes with sulfonamides were developed. Based on the change of the reaction time and atmosphere from N2 to O2, this reaction proceeded in high yields and excellent selectivity under different conditions. Mechanistic details were also described.
