邻巯基氧化吡啶双齿配位的过渡金属(Ni,Pd)化合物NMR研究

Nmr Studies on Transition-Metal(Ni,Pd)Compounds with Bidentate Coordination of O-mercaptopyridine Ligands

本文报道了化合物 Ni(mpo)_2(1)和 Pd(mpo)_2(2)的~1H,^(13)C NMR 的化学位移和偶合常数 J_(H-H)并借助同核和异核二维相关谱,进行分析,归属了~1H,^(13)C NMR 谱线。简单讨论了这两个非对称结构化合物在溶液中的稳定性。

~1H,^(13)C NMR Chemical shifts and coupling constants(J_(H-H))of compounds Ni (mpo)_2(1)and Pd(mpo)_2 (2)have been determined.Analysis of ~1H and ^(13)C NMR spectra with the aid of COSY and HMQC experiments has allowed unambiguous chemical shift as- signments of protons and carbons of the compounds.It was briefly discussed that this unsym- metrical structure of the compounds is very stable in solution.
