- Electrochemical reduction of cinnamonitrile in the presence of carbon dioxide: Synthesis of cyano- and phenyl-substituted propionic acids
-
Cyano- and phenyl-substituted propionic acids were synthesized simply and efficiently by electrocarboxylation of cinnamonitrile in undivided cells using the non-noble metal nickel as cathode and magnesium as the anode. The radical anion generated by the e

- Electrochemical Acylation and Carboxylation of Some Activated Olefins
-
The electrochemical acylation and carboxylation of some activated olefins have been investigated.Acenaphthylene yields thus on reductive electrochemical acetylation mainly the Z and E enol acetates of 1-(1,2-dihydro-1-acenaphthylidene)ethanone, whereas carboxylation followed by methylation gives trans-1,2-dimethoxycarbonyl-1,2-dihydroacenaphthene.Ethyl cinnamate can be acylated and carboxylated in the 3-position, whereas benzoylacetone could be carboxylated but not acetylated.Neither carboxylation nor acylation were able to compete with the dimerization of benzylidenemalonitrile.Cyclic voltammetry showed that carboxylation generally was faster than acetylation.
