FSO2 Radical-Initiated Tandem Addition Reaction of Two Different Olefins: A Facile Access to Multifunctional Aliphatic Sulfonyl Fluorides

Multicomponent reactions represent a powerful methodfor buildingcomplex molecules from structurally simple starting materials. Herein,we report a novel three-component radical-polar crossover reactioninvolving a tandem addition reaction of two different olefins, whichis initiated by the selective addition of fluorosulfonyl radicalsto alkyl alkenes. This tandem process provides facile and effectiveaccess to multiple functionalized aliphatic sulfonyl fluoride molecules.Further transformation of the products is also demonstrated.
