Claisen 976 in 1887 modified the Cannizzaro reaction by using sodium ethoxide in place of sodium hydroxide, and found that benzaldeyde was converted to benzyl benzoate. This application Mar. The reaction is named after Stanislao Cannizzaro … Cannizzaro Reaction Mechanism details the method to get one molecule of alcohol and one molecule of carboxylic acid from two molecules of a given aldehyde. 3. at RuO2-coated diamond electrodes showed that conductive metallic oxides are promising electrocatalysts for this process and allow higher redn. products, resp. In the Cannizzaro reaction an aldehyde disproportionates into the corresponding alcohol and acid. Cannizzaro first accomplished this transformation in 1853, when he obtained benzyl alcohol and potassium benzoate from the treatment of benzaldehyde with potash (potassium carbonate). A local alkaline environment near the electrode surface, caused by the hydrogen evolution reaction, initiates aldehyde disproportionation promoted by hydroxide ions, which leads to the formation of the corresponding carboxylic acid and alcohol.
