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 …

WebJul 12, 2024 · PBN is the most commonly used spin-trap in photopolymerization investigations, and the detection of radical species (i.e., acyl, phenyl, phosphinoyl, benzyl, sulfonyl, silyl, germyl, and boryl radicals) generated from PIS has been then systematically generalized by photochemistry groups [ 30, 35, 39, 40, 41, 42] and described as follows. … WebA tandem radical relay strategy was realized for the first Cu(I)-catalyzed enantioselective phosphinocyanation of styrenes. In this reaction, t BuOOSiMe 3 generated in situ from t BuOOH serves as a radical initiator to trigger t-butoxy radical production upon oxidization of L*Cu(I) species via proton-coupled-electron transfer (PCET) pathway, which leads to … WebJun 28, 2024 · Disclosed herein is a novel and practical protocol for the radical-mediated phosphinoyl-functionalization of unactived alkenes.
