25637-16-5, 4-Bromotetrahydropyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Sodium sulphide (42.2 g; 35%; 188.8 mmol) and sulphur (3.33 g; 104 mmol) are suspended in water (120 ml) and the suspension is stirred for 1.5 hours at 60 C. Benzene (250 ml), followed by tetrabutylammonium bromide (0.61 g; 1.89 mmol) and 4-bromo-tetrahydropyran (7.79 g; 47.2 mmol) are added and the entire mixture is stirred at 60 C. for four hours. The reaction mixture is poured on to ice-water and extracted twice with ether. The organic phase is dried over sodium sulphate, the salts are filtered off and the solvent is evaporated off. [01206] Yield: 2.41 g (44%) 4,4′-dithiobis-tetrahydropyran as a yellow oil. MS (ISP): 234 (M)+
