Generation, Characterization, and Reactivity of a Cu^II–Alkylperoxide/Anilino Radical Complex: Insight into the O–O Bond Cleavage Mechanism

Abstract

The reaction of [Cu(I)(TIPT3tren) (CH3CN)]ClO4 (1) and cumene hydroperoxide (C6H5C(CH3)2OOH, ROOH) at -60 °C in CH2Cl2 gave a Cu(II)-alkylperoxide/anilino radical complex 2, the formation of which was confirmed by UV-vis, resonance Raman, EPR, and CSI-mass spectroscopy. The mechanism of formation of 2, as well as its reactivity, has been explored.
