Thermal and Photochemical Reactions of Triarylmethyl Peroxides

Article abstract of DOI:10.1021/jo00262a030

The thermal and photochemical decomposition products of p-benzoyltriphenylmethyl peroxide (I), of m-benzoyltriphenylmethyl peroxide (II), and of isotopically labeled analogues indicate rapid radical 1,2-migrations precluding other radical processes such as β-elimination from the incipient radical.The mechanism of these processes is interpreted in terms of these rearrangements as well as reversible elimination of O2 from the starting peroxide.Differences in the two isomeric peroxides are assessed.
