Relative rate constants for the reactions of hydroxyl radicals with a series of alkyl substituted olefins were measured by competitive reactions between pairs of olefins a t 298 r 2 K and 1 atmospheric pressure. Hydroxyl radicals were produced by the photolysis of H,O, with 254-nm irradiation. The o
It is demonstrated that photohalogenations of low reactivity substrates with BrCl occurs mainly with Cl' selectivity. With tertiary or benzylic hydrogens in the substrate, mainly Br' selectivity is observed. These observations are rationalized, taking into account the relative concentrations of ha
