摘要：
We have determined the activation parameters ΔlogA and ΔE for the Arrhenius equations for the kinetic isotope effect (c-C6H 12/c-C6D12) and the 5/6 effect (c-C 5H10/c-C6H12) in reactions of the C-H bonds of cycloalkanes with HOCl in aqueous solutions in the interval 30-90°C. The data obtained are consistent with a chlorination mechanism including a pre-activation step with formation of an HO• ... Cl• pair, linear abstraction of the H atom by the OH group and angular attack by the Cl atom "at a distance" on the carbon atom. ©2004 Springer Science+Business Media, Inc.
