Unsymmetrical peroxides could be prepared easily by reaction of alkyl hydroperoxides with primary and secondary alkyl bromides and methanesulfonates in tetrahydrofuran in the presence of potassium hydroxide and polyethyleneglycol 400.

system using tetraalkylammonium salts as phase-transfercatalysts is reported. This process was conducted in the presence of highly concentrated aqueous KOH solutions and cyclohexane as an organic solvent. In a liquid–liquid–liquid system, the phase-transfercatalyst forms an insoluble third-liquid phase between the organic and aqueous phases that enables the catalyst to be recycled multiple times.
