  摘要：

  与反应性研究的双-螯合的Pd（II）膦基iminolate络合物[钯（DMBA）（κ 2 - P，ö -PPh 2 Ñ C（O）Me）的]（2）（DMBA =邻位二甲基苄胺）已经表明它容易地作为金属配体与造币金属的亲电子配合物发生反应，选择性地通过P，O螯合物的氮原子发生反应。在检查了其与AgOTf（OTf = SO 3 CF 3）的反应后，我们得到了第一个含Ag-Pd键的1-D配位聚合物[{Ag（2）} OTf] n（3 ·OTf）。将其反应与H +，Au（PPh3）+，[AuCl（THT）]，[Au（THT）] BF 4和[Cu（NCMe）4 ] BF 4。根据所使用的亲电金属试剂的性质，2的亚氨基N原子之间的相互作用亲电子试剂可以被正式描述为涉及其孤对的配位键，它将正式将络合物的正电荷更多地置于造币金属上，或者被视为更共价的相互作用，从而导致碳氧键顺序增加，从而正/基本电荷更多地位于

• Enolphosphato−Phosphines:  A New Class of P,O Ligands

  The new bifunctional ligands Ph2PCH=CPh[OP(O)(OR)(2)] (1) (1a, R = Et; 1b, R = Ph) represent the first examples of P,O derivatives resulting from the association of a phosphine moiety and an enolphosphate group. The Z stereochemistry about the double bond provides a favorable situation for these ligands to act as P,O-chelates. Neutral and cationic Pd(II) complexes have been synthesized and characterized, in which 1a or 1b acts either as a P-monodentate ligand or a P,O-chelate, via coordination of the oxygen atom of the P=O group. In the latter case, it has been observed that phosphines 1a and 1b can display a hemilabile behavior, owing to successive dissociation and recoordination of the O atom. Competition experiments revealed that phosphine la presents a higher chelating ability than 1b, a feature ascribed to the more electrodonating properties of the ethoxy groups in 1a compared to the phenoxy groups in 1b. P,O-Chelation affords seven-membered metallocycles, which is unusual for RO-chelates. Complexes trans-[PdCl2Ph2PCH=C(Ph)OP(O)(OPh)(2)}(2)] (2b), [PdClPh2PCH=C(Ph)OP(O)(OEt)(2)}(mu-Cl)](2) (3a), [Pd(dmba)Ph2PCH=C(Ph)OP(O)(OEt)(2)}][PF6] (8a'), and cis-[PdPh2PCH=C(Ph)OP(O)(OEt)(2)}][BF4](2) (10a) have been structurally characterized. Interestingly, the seven-membered rings in 8a' and 10a adopt a sofa conformation with the double bond lying almost perpendicular to the plane containing the Pd, the two P, and the two O atoms.
