Indirect Electrochemical Oxidation of Aryl Alkyl Ketones Mediated by NaI–NaOH System: Facile and Effective Way to α-Hydroxyketals
摘要:
Indirect electrochemical. oxidation of aryl alkyl ketones in methanol in an undivided cell in the presence of sodium iodide-sodium hydroxide leads to the corresponding alpha -hydroxyketals in 75-85% substance yield (70-75% current yield). (C) 2000 Elsevier Science Ltd. All rights reserved.

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.
