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.
A process for preparing an alcohol by electrochemical reductive coupling, the process comprising providing an electrolyte solution comprising an aromatic vinyl compound, a carbonyl compound, and a non-aqueous protic solvent in an electrochemical cell, and electrolyzing the electrolyte solution in the cell, wherein the electrolyte solution is in contact with a carbon-based cathode;
A process for preparing an alcohol by electrochemical reductive coupling, the process comprising providing an electrolyte solution including an aromatic vinyl compound, a carbonyl compound, a nitroxyl compound, a conducting salt, and a non-aqueous protic solvent in an electrochemical cell, and electrolyzing the electrolyte solution in the cell, wherein the electrolyte solution is in contact with a carbon-based cathode selected from the group consisting of a graphite electrode, a gas diffusion layer electrode, a carbon felt electrode and a graphite felt electrode;
