The reaction of [Cu-I(TIPT(3)tren) (CH3CN)]ClO4 (1) and cumene hydroperoxide (C6H5C-(CH3)(2)OOH, ROOH) at-60 degrees 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.
