NOVEL OXIDATIVE CLEAVAGE OF CARBON-CARBON BOND IN HYDRAZONES BY OXYGENATION WITH COBALT SCHIFF BASE COMPLEX

Article abstract of DOI:10.1016/S0040-4039(00)84608-0

Oxygenation of aromatic ketone hydrazones with Co(salen) in methanol resulted unexpectedly in oxidative degradation to give methyl benzoate derivatives.A mechanism involving nucleophilic attack by methanol on a diazo intermediate is discussed.
