Heating a suspension of the monomeric hydroxo palladium complex of the type [Pd(N-N)(C6F5)(OH)] (N-N = bipy, Me2bipy, phen or tmeda) in methylketone (acetone or methylisobutylketone) under reflux affords the corresponding ketonyl palladium complex [Pd(N-N)(C6F 5)(CH2COR)]. On the other hand, the reaction of the hydroxo palladium complexes [Pd(N-N)(C6F5)(OH)] (N-N = bipy, phen or tmeda) with diethylmalonate or malononitrile yields the C-bound enolate palladium complexes [Pd(N-N)(CHX2)(C6F 5)] (X = CO2Et or CN), and the reaction of [Pd(N-N)(C 6F5)(OH)] (N-N = bipy or phen) with nitromethane gives the nitromethyl palladium complexes [Pd(N-N)(CH2NO2)(C 6F5)]. [Pd(tmeda)(C6F5)(OH)] catalyses the cyclotrimerization of malononitrile. The crystal structures of [Pd(bipy)(C6F5)(CH2COMe)]·1/2Me 2CO, [Pd(tmeda)(C6F5){CH(CO2Et) 2}], [Pd(tmeda)(C6F5){CH(CN)2}] and [Pd(tmeda)(C6F5)(CH2NO2)]·1/ 2CH2Cl2 have been established by X-ray diffraction.
