Abstract
|
|
|
|
The pseudo-first order rate constants have been obtained for the solvolysis of pseudo-saccharinechloride in MeOH-H2O, EtOH-H2O, MeOH-MeCN and MeOH-(Me)2CO solvents mixtures at various temperatures. Values of n and m in the Kivinen and Grunwald-Winstein plots, respectively, have been determined and the Taft's solvatochromic parameters were obtained; based on these solvent effect parameters as well as on the activation parameters it was concluded that reaction proceeds via an SN2 mechanism.
