Reaktionsschritte

Alpha-pinene (38 g, 0.28 mol) and 2,5-dimercapto-1,3,4-thiadiazole (40 g, 0.27 mol) were charged to the reaction flask and cautiously heated to 155° C. since the reaction was exothermic. The reaction was maintained at 155° C. for 15 min. and then cooled. Isopropanol (32 g) and n-octylmercaptan (43.7 g, 0.30 mol) were charged. Hydrogen peroxide, 35% (60 g, 0.62 mol) was added slowly while maintaining the temperature at 40°-50° C. The reaction was then allowed to stand overnight. The product was extracted with 150 ml of n-hexane and washed with 150 ml of 1M sodium carbonate. The organic layer was dried over magnesium sulfate, filtered, and the solvent removed by rotary evaporation.
