含手性膦配体MBPA和邻巯基吡啶配体PyS的过渡金属钯(Ⅱ)化合物的2D NMR研究

2D NMR Studies of Transition-Metal Pd (Ⅱ) Compounds Containing PyS Ligands and Chiral Phosphine Ligands MBPA

利用一维和二维NMR技术,对含手性膦配体MBPA和邻巯基吡啶配体PyS的过渡金属Pd(Ⅱ)化合物Pd(3-MBPA)(PyS)Cl)(1),Pd(2-MBPA)(PyS)Cl)(2)。进行~1H和^(13)C NMR谱分析,归属了所有的~1H和^(13)CNMR谱线,并对配体在配位前后的化学位移的变化作了简单讨论。

Analysis of ~1H and ^(13)C NMR spectra of transition-metal Pd (Ⅱ) compounds, containing PyS ligand and chiral phosphine ligands MBPA: Pd ((3-MBPA) (PyS) CD (1), Pd ((2MBPA) (PyS) CD (2) with the aid of H-H COSγ, H-C HMQC experiments, has allowed unambiguous chemical shift assignments of all protons and carbons of the compounds. The difference in chemical shifts of free and coordinate ligands is briefly discussed.
