Electrochemical methoxylation at the active methylene group of phenylacetates and 1-naphthaleneacetate was conducted successfully at room temperature, in methanol containing potassium iodide as an electron carrier and solium methoxide as a bade and a methoxylating agent. Along with the mono-methoxylated products, dimethoxy, hydroxy, and oxo derivatives as well as the dimers (succinates) were produced as by-products.
