An accelerating-reporting group for studies of radical heterolysis reactions and its application in an acid-catalyzed fragmentation reaction of an α,β-dimethoxy radical
The 2,2-diphenylcyclopropyl group was employed to accelerate reactions of α-methoxy radicals containing β-leaving groups, to trap the products of either migration or heterolysis of the leaving group, and to provide a useful chromophore for laser flash pho
