An unusually strong promoter effect on Pd catalysts is obtained from the complex [CdPd(CH 3 COO) 4 ⋅CH 3 COOH] 2 (depicted on the right), which could be isolated from a solution of Pd(OAc) 2 and Cd(OAc) 2 in acetic acid. In the total oxidation of ethylene, supported catalysts prepared from this precursor complex exhibited a higher catalytic activity than catalysts prepared from binary palladium acetate.
