Cationic nitrile platinum(II) complexes of formula [PtMe(RCN)(bipy)]+ undergo nucleophilic addition of carbanions −CH(COX)(COY) (X, Y= Me, OMe), −CH(CO2Me)CN and −CH(CN)2 to afford neutral products. According to the nature of the nucleophile, the organic ligand fragment displays either an imino enol or an enamine isomeric structure. The Pt−N bond can be cleaved upon reaction with acids with formation
式 [PtMe(RCN)(bipy)]+ 的阳离子腈铂 (II) 配合物经历碳负离子的亲核加成 -CH(COX)(COY) (X, Y= Me, OMe), -CH(CO2Me)CN 和 - CH(CN)2 提供中性产物。根据亲核试剂的性质,有机配体片段呈现亚氨基烯醇或烯胺异构结构。Pt-N 键可以在与酸反应时裂解,形成相应的 β-烯氨基二酮。
