Using bis(trimethylsilyl) peroxide as the oxidant and simply exchanging dichloromethane, the classical solvent for Baeyer-Villiger oxidation, for the ionic liquid bmimNTf2, results in increased product yields. 1-Butyl-3-methylimidazolium trifluoromethanesulfonate can replace both the solvent and BF3OEt2 as catalyst. This method gives lactones in high yields with the possibility of ionic liquid recycling.
