  2. Cumene process - Wikipedia

    en.wikipedia.org/wiki/Cumene_process

    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 from another cumene molecule. This ...
