ABSTRACT:
Activated olefinically unsaturated organic compounds such as esters, acids, ketones, nitriles, and the like, are reacted with hydrogen sulfide in the presence of at least one of magnesium oxide and anion exchange resins catalysts to produce saturated sulfur-containing compounds. In a specific embodiment, unsaturated carboxylates are converted in high yields to mercaptoalkanoates.
