Solvation models in the reaction between benzyl bromide and s-triazole dictions of the reaction mechanisms have been obtained from such studies.

Abstract

The kinetics of nucleophilic substitution on benzyl bromide by s-triazole has been studied in different pure (protic and aprotic) solvents. The reaction is overall second order, with first order dependence on [benzyl bromide] and the [nucleophile].The rate data is correlated with different solvent parameters using linear multiple regression analysis. From the regression coefficients, information on the solvent-reactant and the solvent-intermediate interactions is obtained and the solvation models are proposed. The reaction has also been studied at different temperatures and the thermodynamic parameters <img src='http://www.niscair.res.in/jinfo/delta.gif' border=0><em>H</em>^≠, <img src='http://www.niscair.res.in/jinfo/delta.gif' border=0> <em>S</em>^≠ and <img src='http://www.niscair.res.in/jinfo/delta.gif' border=0> <em>G</em>^≠ are computed.
