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%)

Catalyzed by silver salt, the unactivated C(sp3)–H heteroarylation of free alcohol at the δ position is realized under gentle thermal conditions in water through a radical procedure. Both protonic acids and Lewisacids are found to be efficient for activating pyridines for this Minisci-type reaction. The reaction enjoys a good functional group tolerance and substrate scope.

The use of polyhedral oligomeric silsesquioxane (POSS) as a solublesupport in organic synthesis is reported. A POSS-bound isocyanate was readily synthesised in one step from commercially available starting materials and was isolated in high yield and purity by simple filtration. It was found to perform well as a scavenger for excess amine in the solution phase synthesis of amides and sulfonamides
