The oxidation of bicyclo[2.1.0]pentane by isolated dimethyldioxirane and by the more powerful methyl(trifluoromethyl)dioxirane, affords selectively, the corresponding endo-2 alcohol along with the 2,3-diol in high yield, and no rearrangement products; this suggests that a concerted O-insertion mechanism should be preferred over radical pathways.

Three structurally analogous radical clock substrates with a 100-fold span in their rearrangement rates are hydroxylated by the diiron oxygenase AlkB to afford similar amounts of rearranged and unrearranged products. Such a result is predicted by a mechanistic scheme by which radical rebound competes with cage escape of the geminate substrate radical. The results show that radical clocks can measure both the radical life-time and the kinetics of cage escape.
