The stoichiometric oxidation of ethylene by Pd(NO(n))mCl2-mL2 complexes (where n = 2, 3; m = 0, 1, 2; L = CD3CN) in chloroform-acetic acid solution was studied with H-1 NMR. This reaction becomes catalytic in the presence of oxygen. The product distribution depends on the nature of the ligands and on the solvent composition. The reaction leads mostly to acetaldehyde, nitroethylene, ethylene glycol monoacetate, and 1,1-disubstituted ethanes. Kinetics and spectral data indicate the formation of a number of intermediates. The mechanism of ethylene oxidation to 1,1- and 1,2-addition products is discussed.
