ELECTROCHEMICAL TRANSFORMATION OF CYANOACETIC ESTER AND ALKYLIDENECYANOACETIC ESTERS INTO 3-SUBSTITUTED 1,2-DICYANOCYCLOPROPANE-1,2-DICARBOXYLATES

Electrolysis of cyanoacetic ester and alkylidenecyanoacetic esters in an undivided cell in the presence of mediators (alkali metal halides) gives rise to 3-substituted, 1,2-dicyanocyclopropane-1,2-dicarboxylates in 60–95% yields.
