摘要：
Pd(PPh3)(4)-catalyzed decarbonylation of the phosphaketene Mes*PCO (1, Mes* = 2,4,6-(t-Bu)(3)C6H2, gives the diphosphene Mes*P = PMes*(2). Related reactions of 1 with zerovalent Pd and Pt phosphine complexes afford diphosphaureylene complexes ML2[Mes*PC(O)PMes*] (L-2 = chelating diphosphine), whose structure and properties depend markedly on the metal and ancillary ligands; Pd(dppf)[Mes*PC(O)PMes*] (12, dppf = 1,1'-bis(diphenylphosphino)ferrocene) also catalyzes the title reaction.
