摘要: 利用一维和二维NMR技术,对含有手性膦配体的铂配合物trans-[Pt(3-MBPAH)2Cl2](1)和trans-(Pt(3-MBPA)(3-MBPAH)Cl)(2)进行1H和13C NMR谱分析,否定了化合物(2)的结构为trans-[Pt(3-MBPA)2]的可能,归属了所有的1H和13C NMR谱线,并根据磷和铂及磷与磷的偶合常数确定它们是反式构型.

Abstract: The 1H、13C and 31P NMR spectra of platinum complexes (1)and (2)have been measured. The analysis of 1D NMR spectra of complex (2)indicates that it is not[Pt(3-MBPA)2], but[Pt(3-MBPAH) (3-MBPA) Cl].The 1H-1H COSY and 1H-13C HMQC 2D NMR techniques were used to analyze and assign the 1H and 13C NMR spectra of platinum complex trans-[Pt(3-M BPAH)2Cl2] (1)and trans-[Pt(3-MBPA) (3-MBPAH) Cl] (2). The trans geometry of the complex has been determined by means of the coupling constants (1JP-Pt, 2JP-P)
