of [Rh(COD)Cl](2) with the ligand RN(PX(2))(2) (1: R=C6H5; X=OC6H5) give mono- or disubstituted complexes of the type [Rh-2(COD)Cl-2eta(2)-C6H5N(P(OC6H5)(2))(2)}-] or [RhCleta(2)-C6H5N(P(OC6H5)(2))(2)}](2), depending on the reaction conditions. Reaction of 1 with [Rh(CO)(2)Cl](2) gives the symmetric binuclear complex, [Rh(CO)Clmu-C6H5N(P(OC6H5)(2))(2)}], whereas the same reaction with 2 (R=CH3; X=OC6H5)
[Rh(COD)Cl](2)与配体RN(PX(2))(2)的反应(1:R = C6H5; X = OC6H5)得到[Rh-2( COD)Cl-2 eta(2)-C6H5N(P(OC6H5)(2))(2)}-]或[RhCl eta(2)-C6H5N(P(OC6H5)(2))(2)} ](2),取决于反应条件。1与[Rh(CO)(2)Cl](2)反应得到对称的双核络合物[Rh(CO)Cl mu-C6H5N(P(OC6H5)(2))(2)}],而与2(R = CH3; X = OC6H5)的相同反应导致形成[Rh(CO)(mu-CO)Cl mu-CH3N(P(OC6H5)(2))(2 )}]同时包含末端和桥接CO基团。有趣的是3(R = C6H5,X = OC6H4Br-p)与[Rh(COD)Cl](2)或[Rh(CO)(2)Cl](2)的反应仅导致氯的形成桥接双核复合物[RhCl e

The reactions of [MCl2(cod)] (M = Pd or Pt, cod = cycloocta-1,5-diene) with RN[P(OPh)2]2 [R = Me (L1) or Ph (L2)] afford the chelate complexes [MCl2L1] and [MCl2L2]. The dinuclear palladium(0) complex, [Pd2L1(3)] has been synthesized by starting from [Pd2(dba)3] (dba = dibenzylideneacetone). Redox condensation of [Pd2(dba)3] and [PdCl2(PhCN)2] in the presence of the diphosphazane ligands gives the dinuclear palladium(I) complexes [Pd2Cl2L12] and [Pd2Cl2L22]. The structures of the complexes have been deduced from H-1 and P-31 NMR spectroscopic data. Single-crystal X-ray diffraction studies confirm the structures of [Pd2L1(3)] and [Pd2Cl2L22].
