Water was found to be a highly efficient and green catalyst and solvent for ring-opening reaction of epoxides with Na2S at room temperature to give substituted bis(hydroxyethyl)thioethers in high yields.

The reactions of β,β'-dichlorodialkyl sulfides and β,β'-dichlorodialkyl sulfones with Na2S and Na2S2 were studied, and the extraction power of the reaction products with respect to Au(III) and Pd(II) was examined.

The kinetics of the liquid-phase reaction of hydrogen sulfide with propylene oxide was studied. In the presence of excess epoxide, the reaction occurred in two successive macrostages: (1) formation of 2-hydroxypropane-1-thiol and (2) formation of 1,1′-di(2-hydroxypropyl) sulfide. Both of the stages are autocatalytic. 2-Hydroxypropane-1-thiol was mainly formed in the presence of excess H2S. The overall third order of the reaction (the first with respect to each reagent and to 2-hydroxypropane-1-thiol) was found. A kinetic scheme was proposed, and the rate constants of particular stages were calculated. The influence of various catalysts (active carbon, ion-exchange resins, metal oxides, and others) was studied, and the relative efficiency of some of them was determined.
