Electrocchemicai oxidatiob of ketones in methanol in the presence of alkali metal bromides
摘要:
Electrochemical oxidation of methyl ketones in methanol in the presence of alkali metal bromides affords methyl carboxylates. Benzyl alkyl ketones are transformed under similar conditions into methyl 3-phenylalkanoates, while ketones lacking alpha-benzyl or alpha-methyl group are oxidized into alpha-hydroxyketals.
