Abstract: Alcohols are prepared by electrochemical reductive coupling of an aromatic vinyl compound and a carbonyl compound in a process which comprises electrolyzing an electrolyte solution in an electrochemical cell, the electrolyte solution comprising the aromatic vinyl compound, the carbonyl compound and a non-aqueous protic solvent, such as methanol, wherein the electrolyte solution is in contact with a carbon-based cathode Styrene is reacted with acetone to prepare 2-methyl-4-phenyl-2-butanol.

Abstract: This invention refers to a process of anodic substitution comprising the electrolyzing the liquid reaction medium in an electrochemical cell comprising a cathode and an anode, whereas the liquid reaction medium comprises an organic compound with at least one carbon bound hydrogen atom, a nucleophilic agent, and an ionic liquid in a proportion of at least 10% by weight, and whereas the said hydrogen atoms are replaced at least partially with the nucleophilic group of said nucleophilic agent. Preferably, a gas diffusion layer electrode is used as anode.
