We report the first successful realization of sulfenylation/phosphorylation of unactivated alkenes via thianthrenation. This strategy achieves regioselective C-S/C-P bond formation in one pot by reacting alkenylsulfonium salts with diaryl disulfides and P(O)-H reagents under basic conditions. The transition-metal- and catalyst-free protocol features mild reaction conditions and broad substrate compatibility, affording a new approach for the selective construction of sulfur- and phosphorus-embedded molecular architectures.
