“…In 1,2-dimethoxyethane, the rate is similar to that observed in acetic acid under comparable conditions, but is slower in such solvents as nitromethane, dioxane, ethyl acetate and ethyl ether, possibly due to poor solubility of PdCl, and sodium acetate in these solvents. 3. Acetate has been found to accelerate the rate and chloride to act as an inhibitor.…”
