Mn. Elinson et al., ELECTROCHEMICAL TRANSFORMATION OF MALONATE AND ALKYLIDENEMALONATES INTO 3-SUBSTITUTED CYCLOPROPANE-1,1,2,2-TETRACARBOXYLATES, Mendeleev communications, (1), 1998, pp. 15-17
Electrolysis of malonate and alkylidenemalonates in an undivided cell
in methanol in the presence of sodium bromide or sodium iodide as medi
ators leads to substituted 1,1,2,2-cyclopropanetetracarboxylates in 80
-95% substance and 60-75% current yield.
