Abstract

The kinetics of the reactions of hydroxy radicals with cyclopropane and cyclobutane has been investigated in the temperature range of 298–492 K with laser flash photolysis/resonance fluorescence technique. The temperature dependence of the rate constants is given by k1 = (1.17 ± 0.15) × 10−16 T3/2 exp[−(1037 ± 87) kcal mol−1/RT] cm3 molecule−1 s1 and k2 = (5.06 ± 0.57) × 10−16 T3/2 exp[−(228 ± 78) kcal mol−1/RT] cm3 molecule−1 s−1 for the reactions OH + cyclopropane → products (1) and OH + cyclobutane → products (2), respectively. Kinetic data available for OH + cycloalkane reactions were analyzed in terms of structure‐reactivity correlations involving kinetic and energetic parameters.
