Preparation of Cyclohexane, 1,2-dibromo-, (1R,2R)-rel-: Firstly, adding cyclohexene, carbon tetrachloride and ethanol to beaker. Then bromine and carbon tetrachloride solution is added dropwise in 3 hours at the temperature below 1 °C. After reaction, carbon tetrachloride is steamed in water bath and the residue is washed by 20% potassium hydroxide solution and water. At last, product is obtained by vacuum distillation and drying. The yield is about 85%.
