The influence of solvent on the proton transfer reactions of substituted 3-OHTRN has been examined using the self-consistent isodensity polarized continuum model (SCI-PCM) in water. As a result, while the proton transfer reaction is kinetically the easiest by substitution on position 3 of -NH2 group in the gas phase, it is kinetically the easiest by substitution on position 5 of the same group in water. In addition, these reactions are either kinetically or thermodynamically easier in the gas phase than that in water, except the reaction of structure with -NH2 group at position 6.en10.14102/j.cnki.0254-5861.2010-1628info:eu-repo/semantics/closedAccess3-hydroxytropolone; Density functional theory; The proton transfer reaction; Tropolone derivativeArticle3312176717572-s2.0-84918578565Q3
