One-electron oxidative cleavage of palladium(II) alkyl and phenoxo bonds

One-electron oxidation of the d 8 dialkyls Pd(CH 3 ) 2 (dmpe), Pd[CH 2 Si(CH 3 ) 3 ] 2 (dmpe), and Pd(CH 3 )(P(t-Bu) 2 - (CH 2 ) 2 CH(CH 2 ) 2 P(t-Bu) 2 ], where dmpe=1,2-bis(dimethylphosphino)ethane, by chemical or electrochemical methods results in homolytic cleavage of the Pd-alkyl bond to produce an alkyl radical and the corresponding cationic palladium(II) monoalkyl complex
