Alkylation of alkali metal salts of hydroperoxides with haloalkanes in dipolar nonhydroxyl solvents
摘要:
The possibility of alkylation with chloroalkanes of cumyl hydroperoxide sodium salt hexahydrate in dopolar nonhydroxyl solvents with high donor numbers was examined. The kinetic featutes of the process in hexamethylphosphoric triamide were studied.

green methods for their synthesis are still being sought. Herein, ultrasound-assisted synthesis of dialkyl peroxides from alkyl hydroperoxides and alkyl bromides in the presence of an aqueous solution of an inorganic base was systematically studied underphase-transfer catalysis (PTC) conditions. The process run in a tri-liquid system in which polyethylene glycol as a phase-transfer catalyst formed a third

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.
