Leaving group property of dimethyl sulfide.

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