Generation, Characterization, and Reactivity of a CuII–Alkylperoxide/Anilino Radical Complex: Insight into the O–O Bond Cleavage Mechanism
摘要:
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.

The toxic halogenated anilines 2,4,6-tribromoaniline, 2,4,6-trichloroaniline and their dibromochloro and bromodichloro derivatives were considered as compounds of exclusive synthetic origin. Labeling studies and kinetic experiments confirmed that these substances are also biosynthesized by a marine biofilm forming microalga. They represent a novel class of halogenated natural products.
