Electroreductive acylation of 3-aryl substituted α,β-unsaturated esters and nitriles in the presence of aliphatic carboxylic anhydrides using areactive metal anode (Mg, Al, Zn) in an undivided cell afforded the corresponding β-acyl compounds in moderate to good yields. It was found that anionic species formed by electron transfer from a cathode may be stabilized by metal ions freshly formed from an

Complexation of electroactive substrates with β-cyclodextrin can profoundly alter the course of their reactions; for the cathodicreduction of complexes of ethyl cinnamate, benzaldehyde, and benzophenone protonation of radical-anions is highly efficient whereas a previously unobserved reductive coupling is found for the acetophenone complex.
Electroreductive silylation of alpha, beta-unsaturated esters, nitriles and ketones in the presence of Me3SiCl using a reactive metal anode (Mg, Zn, Al) in an undivided cell afforded the corresponding beta-silyl compounds offering a valuable method for introduction of a silyl group into activated olefins.
