The functionalization of saturated hydrocarbons. Part 20. Alkyl hydroperoxides: reaction intermediates in the oxidation of saturated hydrocarbons by Gif-type reactions and mechanistic studies on their formation

“…. The relative reactivity of cyclopentane and cyclohexane (C5/C6) is a useful criterion for establishing the mechanism of C-H bond cleavage 39. For several different radical-chain reactions, carbon-hydrogen bonds in cyclopentane are more reactive than those in cyclohexane, and C5/C6 ratios greater than unity are obtained.13•23,40 In Gif chemistry, however, cyclohexane is…”
