WebOct 14, 2024 · In both systems, the initial nucleophilic attack may be accompanied by favorable five-membered ring formation involving a carbonyl ligand, a (reversible) pathway competitive with formation of the three-membered ring found in the phosphirane product. A novel radical mechanism is suggested for the new Fp2-catalyzed system. WebIn this investigation we found also that the radical obtained by photolysis of bis(2,2'-biphenylene)phosphorane at -120° appeared to be identical with the radical obtained by electrochemical reduction of the bis(2,2'-biphenylene)phosphonium ion. Irradiation of the phosphorane which has a trigonal bipyramidal (TBP) configuration results in a ...
