Iodosulfonation of alkenes with benzenesulfinic acid - N-iodosuccinimide - Facile preparation of αβ-unsaturated sulfones
Reaction of alkenes and alkenols with N-iodosuccinimide (NIS) and benzenesulfinic acid in dichloromethane at room temperature affords vic-iodophenylsulfonyl adducts in good to high yields. Treatment of the iodosulfones with neutral alumina in dichlorometh

Polystyrene-supported selenosulfonates: Efficient reagents for regio- and stereocontrolled synthesis of vinyl sulfones
Two novel polystyrene-supported selenosulfonates reagents have been developed. As reagents for boron trifluoride catalyzed or AIBN catalyzed addition to olefins were successfully demonstrated and have been used for regioselective synthesis of vinyl sulfon
