WebThe homolytic N-O bond cleavage of 3 and the subsequent silyl migration of the resulting phosphinoyl radical 7 would be key steps in the reaction. AB - Reaction of stable phosphinyl radical 1a with AZADO gave aminoxyphosphine 3 as the primary product by selective radical coupling at 140 °C. Compound 3 decomposed to phosphorane 4, silyl ... WebTFSP can generate a trifluoromethyl radical under photocatalysis, that can be used for azido- or cyano-trifluoromethylation reactions of alkenes. M. Zhang, ... 3-mediated phosphinoyl radical addition followed by CuCN-catalyzed cyanation enables a double-functionalization reaction of alkenes under mild conditions to afford vicinal ...
