  • Electrochemical synthesis and product
    Patent number: 4377453
    Abstract: A liquid-phase electrochemical synthesis is possible wherein a desired charged intermediate would normally be undesirably immediately electrolyzed, by covalently trapping the charged intermediate onto particles of a sulphonated polystyrene, filtering off the liquid, and regenerating the polystyrene in alkali as exemplary to release and hydrolyze the intermediate. Hexamethylbenzene may be electrolyzed in acetonitrile to give, by this process, 1, 3-(2, 4, 5, 6-tetramethyl)-bisacetamidomethylbenzene.
    Type: Grant
    Filed: August 13, 1979
