ring which includes one carbonyl atom of the phthaloyl group. The reaction of 6 with the tridentate ligand PhP(CH2CH2PPh2)2 affords the five-coordinate complex 16 and from [Pt(C2H4)(PPh3)2] and organic halides the platinum(II) complexes trans-[Pt(CH2N-phthaloyl)(Cl)(PPh3)2] (17) and [PtC(O)CH(CH2Ph)N-phthaloyl(Cl)(PPh3)2] (18) were isolated. The structures of 2, 11, 14, 15 and 16 were determined by single-crystal
通过将 N-邻苯二甲酰甲基或 -乙酰卤化物氧化加成到羰基金属酸盐或 Pd(PPh3)4 或 [Pt(C2H4)(PPh3)2] 上,合成了以 N-邻苯二甲酰基为氨基保护基团的新型氨甲基和氨基乙酰配合物,得到 [ ReC(O)CH2N-邻苯二甲酰基}(CO)5] (1), [FeCp(CH2N-邻苯二甲酰基)(CO)2] (2), [FeCpC(O)CH2N-邻苯二甲酰基}(CO)2 ] (3), trans-[PdBr(CH2N-phthaloyl)(PPh3)2] (4) and trans-[PdC(O)CH2N-phthaloyl}(X)(PPh3)2] (X = Br, Cl ; 5, 6)。双(膦)配合物[Pd(CH2N-邻苯二甲酰基)(X)(R2PCH2CH2PR2)]和[PdC(O)CH2N-邻苯二甲酰基}(X)(R2PCH2CH2PR2)](X = Cl, Br; R
