Reactions of 2-Chloroethyl sulfides: III. Mechanism of methanolysis of 2-Chloroethyl sulfides

The products and kinetics of methanolysis of 2-chloroethyl methyl sulfide, 2-chloroethyl 2-methoxyethyl sulfide, 2,2′-dichlorodiethyl sulfide, and 2-chloroethyl phenyl sulfide (at a concentration of 0.05-0.2 M) were studies by 13C NMR spectroscopy and gas-liquid chromatography. The rate of methanolysis decreases in the following series: methyl > methoxyethyl > 2-chloroethyl > phenyl. The amount of sulfonium dimers among the products decreases in the same series; the rate of dimerization of 2-chloroethyl methyl sulfide exceeds the rate of methanolysis. The reaction of 2-chloroethyl sulfides in methanol with a strong neutral nucleophile, thiourea, is of the second order. The rate constants of this reaction show a correlation with the constants σ* of substituents on the sulfur, which is similar to that found for the hydrolysis. This correlation indicates formation of intermediate ethylenesulfonium ion. Unlike the hydrolysis process, the rate-determining stage in the methanolysis is the reaction of ethylsulfonium ion with the nucleophile rather than ionization of 2-chloroethyl sulfide.
