As illustrations of the participation in electrolytic reductive coupling of a variety of Michael acceptors, data are presented on the hydrodimerization of benzalacetone, mesityl oxide, diethyl vinylphosphonate, diphenylvinylphosphine oxide, and methyl vinyl sulfone and on the mixed reductive couplings of the pairs diethyl fumaratemethyl vinyl ketone, benzalacetone-acrylonitrile, mesityl oxide-acrylonitrile, and methyl vinyl sulfone-N, N- ...
