| Abstract
| - Grossi and Strazzari have reported (J. Org. Chem. 2000, 65,2748−2754) that the ceric ammonium nitrate modulatedphotooxidation of triphenylmethanol and 1,1-diphenylethanolyielded ESR spectra of the putative spiro-cyclohexadienylintermediates in the O-neophyl rearrangements of the corresponding alkoxyl radicals, Ph2(R)CO• (R = Ph, CH3), tothe phenoxymethyl radicals, Ph(R)C•OPh. Both ESR spectraare reassigned to the phenoxyl radical, C6H5O•, and theprobable mechanism by which phenoxyl is formed in thesesystems is presented.
