Electrochemical reduction of carbon diselenide and preparation of 4,4′,5,5′-tetra(selenomethoxy)tetraselenafulvalene

Carbon diselenide has been electrochemically reduced and methylated to form 4,5-di(selenomethoxy)-1,3-diselenole-2-selone from which 4,4′,5,5′- tetra(selenomethoxy)tetraselenafulvalene was prepared.
