Authors investigated the reaction of dioctanoyl peroxide with carbon tetrabromide in carbon tetrachloride.In this reaction heptyl radical, produced by the decomposition of dioctanoyl peroxide, scarcely attacked carbon tetrachloride but attacked carbon tetrabromide to give 1-heptyl bromide. The yield of 1-heptyl bromide was 54.1% at the optimum condition (carbon tetrabromide/dioctanoyl peroxide mole ratio 2; concentration of dioctanoyl peroxide in carbon tetrachloride 0.5mol%; reaction temperature 70°C; reaction time 24hr). By-products of this reaction were tetradecane, caprylic acid, heptyl caprylate, bromoform and hexabromoethane. |
