6-(t-Bu)3C6H2) gives the diphosphene Mes*PPMes* (2). Related reactions of 1 with zerovalent Pd and Pt phosphine complexes afford diphosphaureylene complexes ML2[Mes*PC(O)PMes*] (L2 = 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.
Pd(PPh 3)4催化膦烯Mes * PCO(1,Mes * = 2,4,6-(t-Bu)3 C 6 H 2)的脱羰基反应得到二膦Mes * P PMes *(2)。1与零价Pd和Pt膦配合物的相关反应可得到二磷脲基配合物ML 2 [Mes * PC(O)PMes *](L 2 =螯合二膦),其结构和性质明显取决于金属和辅助配体。Pd(dppf)[Mes * PC(O)PMes *](12,dppf = 1,1'-双(二苯基膦基)二茂铁)也催化标题反应。

Reactions of Mes*P=C=O (1; Mes* = 2,4,6-(t-Bu)(3)C6H2) with (PPh(3))(2)Pt(C2H4) (2) and (PCy(3))(2)Pt (3; Cy = cyclo-C6H11) give the diphosphaureylene carbonyl complexes (L)(CO)Pt(Mes*PCOPMes*) (4, L = PPh(3); 5, L = PCy(3)), respectively. The structure of 4 was determined by X-ray crystallography. Addition, of dmpe (dmpe = Me(2)P(CH2)(2)PMe(2)) to 4 or 5 gives (dmpe)Pt-(Mes*PCOPMes*) (6).
