Baeyer–Villiger Oxidation of Cyclobutanones with 10-Methylacridinium as an Efficient Organocatalyst

Baeyer–Villiger oxidation of cyclobutanones is achieved in current developed protocol with 10-methylacridinium perchlorate (AcrH+ClO4−) as a novel organocatalyst both with irradiation at room temperature and without irradiation at elevated temperature. Excellent yields of the corresponding lactones are obtained and the possible mechanism has been proposed.
