Using a phosphorus based Mannich condensation reaction the new pyridylphosphines 5-Ph2PCH2N(H)}C5H3(1-Cl) and 2-Ph2PCH2N(H)}C5H3(5-Br)N (1-Br) have been synthesised in good yields (60% and 88%, respectively) from Ph2PCH2OH and the appropriate aminopyridine. The ligands 1-Cl and 1-Br display variable coordination modes depending on the choice of late transition-metal complex used. Hence P-monodentate
使用基于磷的曼尼希缩合反应,已经很好地合成了新的吡啶基膦5-Ph2PCH2N(H)} C5H3(1-Cl)和2-Ph2PCH2N(H)} C5H3(5-Br)N(1-Br)由Ph2PCH2OH和适当的氨基吡啶产生(分别为60%和88%)。取决于所使用的后期过渡金属络合物的选择,配体1-Cl和1-Br显示出不同的配位模式。因此已观察到单核络合物AuCl(1-Cl)(2),AuCl(1-Br)(3),RuCl2(对伞花烃)(1-Cl)(4),RuCl2(p -cymene)(1-Br)(5),RhCl2(Cp *)(1-Cl)(6),RhCl2(Cp *)(1-Br)(7),IrCl2(Cp *)(1-Cl) (8),IrCl2(Cp *)(1'-Cl)(8'),IrCl2(Cp *)(1-Br)(9),顺式/反式-PdCl2(1-Cl)(2)(10 ),顺式/反式-PdCl2(1-Br)
