Abstract The solvolyses of the complexes cis-Pt(L2)X2, where L2 is two NH3 molecules or ethylenediamine and X = Cl−, Br−, or I−, in dimethylsulphoxide solution were studied by 195Pt NMR spectroscopy. The rates followed the order:iodides > bromides > chlorides. Products were identified by their chemical shifts and, where possible, 195Pt15N coupling constants. In general, cis-bis-dimethylsulphoxide
摘要:通过195Pt NMR光谱研究了顺式-Pt(L2)X2配合物在二甲亚砜溶液中的溶剂化,其中L2为两个NH3分子或乙二胺,X = Cl-,Br-或I-。速率遵循以下顺序:碘化物>溴化物>氯化物。通过化学位移和195Pt15N耦合常数(可能的话)来鉴定产物。通常,顺式-双-二甲基亚砜复合物不稳定,只有在添加银离子以除去竞争的卤化物配体时才能看到。还报道了OH-离子与Pt(II)DMSO配合物在水溶液和DMSO溶液中相互作用的研究。
