WebHydroperoxide cumene The interval between 0.9 and 3.0 equiv. (relative to sulfide substrate) was studied and the general trend showed that the sulfide conversion went up and reached completion at 1.3 equiv. Both sulfoxide content and ee remain relatively stable (much greater than 90%) and it is only at the highest peroxide levels ( 2 equiv.) when … Cumene is oxidized in air, which removes the tertiary benzylic hydrogen from cumene and hence forms a cumene radical : The cumene radical then bonds with an oxygen molecule to give cumene peroxide radical, which in turn forms cumene hydroperoxide (C 6 H 5 C (CH 3) 2 O 2 H) by abstracting a benzylic hydrogen … See more The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate … See more Cumene is formed in the gas-phase Friedel–Crafts alkylation of benzene by propene. Benzene and propene are compressed together to a pressure of 30 standard atmospheres at 250 °C in presence of a catalytic Lewis acid.
