FIELD: synthesis of organic sulfur-containing compounds used for making additives for high pressure as syntones in organic synthesis. SUBSTANCE: compounds are prepared by reacting norbornene, endo-or exo- dicyclopentadiene with elementary sulfur at 125-135 C in the presence of catalyst in amount of 0.5-2.0% of weight of norbornene, endo-or exo-dicyclopentadiene N-(dimethylaminomethylene)-1,2,4- triazole. Yield of product is 85-90 %, and said catalyst is not deficient. EFFECT: more efficient preparation method. 5 ex
