Supported Sulfide and Sulfur Oxy-Acid Salts. Involvement of Alumina-Induced Cannizzaro Reaction in the Reported Reduction of Aldehydes by Na2S/Alumina

Cannizzaro type oxidation-reduction of aromatic and aliphatic aldehydes, promoted by alumina, was observed during study of inorganic-solid-supported sodium sulfide and sulfur oxy-acid salts.
