WebJul 24, 2024 · Disclosed herein is a novel and practical protocol for the radical-mediated phosphinoyl-functionalization of unactivated alkenes. The P-centered radicals are generated in the presence of TBHP under mild reaction conditions, which trigger the subsequent distal functional group migration. WebApr 8, 2024 · A series of bifunctional phosphine compounds promising as γ-functionalized phosphine ligand precursors are conveniently synthesized by the radical addition of diphenylphosphine oxide (Ph2P(O)H) to allylic compounds under photoirradiation. The photoinduced addition proceeds regioselectively in an anti-Markovnikov manner, and …
