Abstract
H-sulfoximines react to give new hypervalent iodine(III) reagents, which under photocatalysis transfer difluoroacetoxy and sulfoximidoyl groups to styrenes with high regioselectivity. The results of mechanistic investigations suggest the intermediacy of radicals and reveal the importance of the difluoroacetoxy group on the iodine reagent.
