Solvation model in the allylation of 2-mercaptobenzothiazole
The kinetics of the reaction of allyl bromide with 2-mercaptobenzothiazole has been studied in different protic and aprotic solvents conductometrically. The rate data were correlated with solvation parameters using linear multiple regression analysis. From the regression coefficients, which describe the susceptibility towards rate of different solvent parameters, information regarding solvent interactions is obtained and solvation models are proposed. The reaction has also been studied at different temperatures and thermodynamic parameters a dagger H-not equal, a dagger S-not equal, a dagger G(not equal) are computed.
