Ultrasound-assisted green synthesis of dialkyl peroxides under phase-transfer catalysis conditions
Kope?, Daniel,Baj, Stefan,Siewniak, Agnieszka
, (2020)
The dialkyl peroxides, which contain a thermally unstable oxygen-oxygen bond, are an important source of radical initiators and cross-linking agents. New efficient and green methods for their synthesis are still being sought. Herein, ultrasound-assisted s
β-Peroxyalkyl radicals and their role in the generation of epoxides during the autoxidation of alkenes. An example of the interplay of free radical, peroxide and organometallic chemistries
Courtneidge, John L.,Bush, Melanie
, p. 57 - 76 (1992)
The systematics of the γ-scission reactions of β-peroxyalkyl radicals to yield epoxides have been extended to include variations in the degree of alkylation at the α- and β-carbon atoms and in the nature of the departing alkoxyl radical.The ratios of geometrically isomeric epoxides so produced have been shown to be dependent upon the steric bulk of the Cα- and Cβ-substituents but rather independent of the nature of the departing alkoxyl radical.The relative importance of 1,5-H atom transfer in β-peroxyalkyl radicals has been considered and some evidence forits occurrence adduced.The relevance of these findings to published data for alkene autoxidation is discussed in terms of two competing pathways, in which, it is suggested, steric factors determine the outcome.
Tri-liquid system in the synthesis of dialkyl peroxides using tetraalkylammonium salts as phase-transfer catalysts

experimental part, p. 208 - 213 (2011/02/23)
A highly effective method to synthesise dialkyl peroxides from alkyl hydroperoxides and alkyl bromides in a liquid-liquid-liquid system using tetraalkylammonium salts as phase-transfer catalysts is reported. This process was conducted in the presence of h
Alkylation of alkali metal salts of hydroperoxides with haloalkanes in dipolar nonhydroxyl solvents

, p. 2096 - 2100 (2008/09/17)
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.
