SH2' Type Reactions of Arenesulfonyl Chlorides with Allylic Compounds Catalyzed by a Ruthenium(II) Complex

Article abstract of DOI:10.1246/bcsj.64.3479

In the presence of a catalytic amount of dichlorotris(triphenylphosphine)ruthenium(II), the reactions of arenesulfonyl chlorides with allyl phenyl sulfide and allyl phenyl selenide proceeded smoothly to give allyl phenyl sulfone in high yield as well as the corresponding diphenyl disulfide or diphenyl diselenide.An S_H2'-type mechanism involving the arenesulfonyl radical is proposed.
