We have developed an electrooxidative method for generating cationic palladium complexes [Pd(CH3CN)4][X]2 (X = BF4, PF6, and ClO4) from Pd(OAc)2 and several electrolytes bearing X groups in CH3CN. The system could be integrated into an electrochemical Wacker-type reaction. In the presence of a catalytic amount of TEMPO, the reaction proceeded smoothly to give the corresponding methyl ketones.
