studied and complexes [RhCl(CO)L] (L = L2 (2), L3 (3) and L4 (4)) have been obtained. For L1 only decomposition products have been achieved. All complexes were fully characterised by analytical and spectroscopic methods and the resolution of the crystalline structure of complexes 2 and 3 by single-crystal X-ray diffraction are also presented. In these complexes, the ligands are coordinated via κ2(N,P) to
两个新的N-吡唑,P-次膦酸酯杂配体3-(3,5-二甲基-1 H-吡唑-1-基)丙基二苯基次膦酸酯(L 3)和2-(3,5-二苯基-1 H-吡唑-1给出了-(基)乙基二苯基次膦酸酯(L 4)。这些配体和文献中报道的其他两个配体的反应性(3,5-二甲基-1 H-吡唑-1-基)甲基二苯基次膦酸酯(L 1)和2-(3,5-二甲基-1 H-吡唑-1 -RyCl(CO)2 ] 2(1的基)乙基二苯基次膦酸酯(L 2))已被研究并获得了配合物[RhCl(CO)L ](L = L 2(2),L 3(3)和L 4(4))。对于L 1,仅获得分解产物。通过分析和光谱学方法对所有配合物进行了充分表征,并提出了通过单晶X射线衍射分析配合物2和3的晶体结构的方法。在这些配合物,所述配体经由协调κ 2(N,P)到的Rh(I),七(形成metallocycles 2和4)或八(3)个成员,并完成与一氧化碳羰基和反氯
