Spin Trapping of Benzoyloxycyclohexadienyl Radicals by 2,3,5,6-Tetramethylnitrosobenzene (Nitrosodurene) in the Decomposition of Dibenzoyl Peroxide in Benzene

Abstract
The aroyloxycyclohexadienyl radicals (VIII), the key intermediates iates in the homolytic aromatic aroyloxylation, were detected and identified in the decomposition of dibenzoyl peroxide, bis(4-methylbenzoyl) peroxide, and bis(4-methoxybenzoyl) peroxide in benzene-d6 as spin adducts of nitrosodurene.
