  膦类固醇在应变氨基膦螯合物形成中的作用

  摘要：

  由于与这些物质有关的环应变，从常见金属前体制备四元氨基膦（PN）螯合物的方法大为回避。我们报告了一种简单的合成此类PN金属环的简单方法，该方法使用简单的α-PN配体，类似于小口角二膦甲烷配体的流行类别。已证明庞大的膦取代基对这些螯合物的形成很重要。

  Alkyl and arylplatinum complexes with 1,5-cyclooctadiene ligand, [PtR2(cod)] (R = Me, Ph, C6H4-p-CF3, C6F5), react with secondary phosphines, PHR'(2) (R' = i-Bu, t-Bu, Ph), to afford the mononuclear platinum complexes, cis-[PtR2(PHR'(2))(2)] (1a: R = Me, R' = i-Bu; 1b: R = Me, R' = t-Bu; 1c: R = Me, R' = Ph; 2a: R = Ph, R' = i-Bu; 2b: R = Ph, R' = t-Bu; 2c: R = R' = Ph; 3a: R= C6H4-p-CF3, R' = i-Bu; 3b: R= C6H4-p-CF3, R' = t-Bu; 3c: R = C6H4-p-CF3, R' = Ph; 4a: R = C6F5, R' = i-Bu; 4c: R = C6F5, R' = Ph) in 81-98% yields. Molecular structures of the complexes except for 1a, 1c and 2a were determined by X-ray crystallography. Complex 1b has a square-planar structure with Pt-C(methyl) bonds of 2.083(8) and 2.109(8) angstrom, while the Pt-C(aryl) bonds of 2b-c, 3a-c, 4a and 4c (2.055(1)-2.073(8) angstrom) are shorter than them. Thermal decomposition of 1b, 2a-c, and 3a-c releases methane, biphenyl or 4,4'-bis(trifluoromethyl)biphenyl as the organic products, which are characterized by NMR spectroscopy. The solid product of the thermal reactions of 2b and 2c were characterized as the metallopolymers formulated as [Pt(PR'(2))(2)](n) (5b: R' = Bu-t; 5c: R' = Ph), based on the solid-state NMR and elemental analyses.
