Cationic nitrile platinum(II) complexes of formula [PtMe(RCN)(bipy)] + undergo nucleophilic addition of carbanions − CH(COX)(COY) (X, Y= Me, OMe), − CH(CO 2 Me)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 of the corresponding β‐enaminodione.
