Discovery of redox system enabling C–N–C bonds formation: Unprecedented Aza-Cannizzaro reaction. 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. The introduced surface NaOH triggered Cannizzaro disproportionation of surface-absorbed formaldehyde (HCHO) on Na-CH, resulting in a catalytic transformation of HCHO into less-toxic formate and methoxy salts. The process is a redox reaction in which a hydride is transferred from one substrate to another. Cannizzaro reaction catalyzed by alkali or hydrotalcite-derived Mg-Al oxide.
