Abstract
A system for hydrogenation of organic compounds without a hydrogen gas supply is described. The process involves an electrochemical apparatus for the generation of hydrogen in situ. The simplicity of the experiment allows students to carry out easy experiments in the laboratory and the instructors to introduce the following concepts: electrochemical principles and catalytic and hydrogenation reactions. A sacrificial anode of nickel is used in the electrochemical system with a double function: to permit the use of an undivided cell and activate the cathode surface. Styrene, benzaldehyde, and acetophenone can be hydrogenated with yields over 92%.
