摘要
利用１Ｄ和２ＤＮＭＲ技术．对含有手性膦配体的铑化合物ｔｒａｎｓ－（（３－ＭＢＰＡ）２Ｒｈ（ＣＯ）（１）和ｔｒａｎｓ－（（２－ＭＢＰＡ）２Ｒｈ（ＣＯ）Ｃｌ）（２），进行１Ｈ和１３ＣＮＭＲ谱分析，归属了所有的１Ｈ和１３ＣＮＭＲ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．
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).
