The effect of catalyst composition on the catalytic activity and product composition is investigated. A three-component catalyst system composed of PdCl2(PPh3)(2), Cu(OMe)(2) and Me4NCl shows synergy effects in terms of the MeOH conversion (26%) and DMC selectivity (95%). The reaction performed in the presence of a single-component catalyst PdCl2(PPh3)(2) produces dimethoxy methane (DMM) as a major product with selectivity over 90%, while the addition of Me4NCl or Cu(OMe)(2) to PdCl2(PPh3)(2) results in the increase of DMC selectivity from 2% to 60%.
