It is shown that hydroxylation of saturatedhydrocarbons by hydrogen peroxide occurs under the influence of light. This reaction has been investigated on acyclic, monocyclic and bicyclic hydrocarbons. These reactions were also studied using performic acid as the source of hydroxyl radicals and results compared with those obtained with peracetic acid. As expected, the preferred attack was on tertiary

[structure: see text] The absolute configuration of secondary and tertiary alcohols can be predicted from analysis of the chemical shift behaviors of the CX- and CY-carbons in the presence of (R)- and (S)-Pr(tfc)3 as formulated in the boxes.
