AM1 semi-empirical MO calculations were performed to investigate the mechanism and activation barriers for hydration reactions of substituted 1,2,3-indanetrions. The potential energy profiles for this reactions were composed of one transition state and two intermediates with reactant and product. It was found that theoretical activation barrier, which was determined in this study, was decreased in the order of [OCH3,OCH3] 〉 [CH3,CH3] 〉 [OCH3,H] 〉 [CH3,H] 〉 [H,H] 〉 [Cl,H] 〉 [Cl,Cl] and thus in accord with the experimental rate coefficients
