摘要: 利用1D和2D NMR技术.对含有手性膦配体的铑化合物trans-((3-MBPA)2Rh(CO)Cl)(1)和trans-((2-MBPA)2Rh(CO) Cl)(2),进行1H和13C NMR谱分析,归属了所有的1H和13C NMR谱线,并根据磷和铑的偶合常数及羰基与磷,铑的偶合常数确定它们是反式构型.

Abstract: Analysis of 1H and 13C NMR spectra of Rhodium compounds trans-((3-MBPA)2Rh(CO)Cl)(1) and trans-((3-MBPA)2Rh(CO)Cl)(2),with the aid of H-H COSY,H-C HMQC, H-H LR COSY experiments, has allowed unambiguous chemical shift assignments of all protons and carbons of the compounds.The trans geometry of the compounds has been determined by means of the coupling constants(JP-Rh,JP-CO,JRh-CO).

Key words: Chiral phosphine ligands, 3-MBPA, 2-MBPA, Rhodium compounds, 2D NMR
