| 摘 要： | 采用NMR方法考察了室温和低温(-78～60℃)下Pd2X2(dpm)2(X=NCO-,CH3CO2-,SCN-和NO3-,dpm=Ph2PCH2PPh2)与H2S在CD2Cl2或CDCl3中的反应。结果表明,在X=NCO-和CH3CO2-的情况下,H2S优先与这些Pd配合物的阴离子作用生成相应的共轭酸HX和Pd2(SH)2(dpm)2,后者在H2S存在下又进一步转化为Pd2(SH)2(dpm)2(μ-S);当X=SCN-和NO3-时,反应则生成结构可能为Pd2(H)(SH)(μ-SH)(dpm)2]+的双核Pd配合物。

| Abstract: | The reactions of Pd2X2(dpm)2(X=NCO-,CH3CO,SCN- and NO;dpm = Ph2PCH2PPh2)with H2Sin CD2Cl2 or CDCl3 were studied by NMRat room and low temperature (-78--60 ℃).In the case of X = NCO- and CH3CO2-, H2S at first reacted with the anions of the palladium complexes and generated HX and Pd2(SH)2(dpm)2 that was subsequently converted to Pd2(SH)2(dpm)2(μ-S)in the presence of excess amount of H2S.In the case of X=SCN- and NO3-,the reactions resulted in the formation of a dinuclear palladium complex with a possible structure ofPd2(H)(SH)(μ-SH)(dpm)2]+. |
