Cationicnitrileplatinum(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

Cyclohexadiene-Mo(CO)2Cp cations react stereospecifically with stabilised enolate nucleophiles to give π-allyl complexes which are converted to substituted allylic iodides on treatment with iodine.
