Pd(PPh 3 ) 4 -catalyzed decarbonylation of the phosphaketene Mes*PCO ( 1, Mes* = 2,4,6-(t-Bu) 3 C 6 H 2 ) gives the diphosphene Mes*P PMes* ( 2 ). Related reactions of 1 with zerovalent Pd and Pt phosphine complexes afford diphosphaureylene complexes ML 2 [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.
