Leaving Group Property of Dimethyl Sulfide

The LFER equation log k = sf (Ef + Nf) was used to derive the nucleofuge specific parameters (Nf and sf) for dimethyl sulfide in the series of aqueous alcohols, using the SN1 solvolysis rate constants obtained for X-substituted benzhydryl dimethyl sulfonates 1-5. The slope parameters (sf) are practically independent on the solvent used, while Nf parameters slightly decrease as the polarity of the solvent increases.
