Catalytic Synthesis of Some Sulfur-containing Heterocyclic Compounds. (Review)

Researches on the synthesis of sulfur-containing heterocyclic compounds at the G. K. Boreskov Institute of Catalysis, Siberian Branch of the Russian Academy of Sciences, are reviewed. They include the synthesis of thiolane by the recyclization of THF in hydrogen sulfide; the synthesis thiacycloalkanes by the hydrogenation of thiophenes; the synthesis of 4-methylthiazole by the reaction of SO₂ with methylisopropylideneamine; the synthesis of thiophenes by the heterocyclization of aliphatic compounds of sulfur and dehydrogenation of thiacycloalkanes; the synthesis of thiolane 1,1-dioxide by the hydrogenation of 2- and 3-thiolene 1,1-dioxides and 3-alkoxythiolane 1,1-dioxides; the synthesis of sulfoxides by the oxidation of thiacycloalkanes with atmospheric oxygen.
