Clear , colourless liquid ˇ Solubility in water at 20 ēC 3,2 g/l ˇ D at 20/4: 2,89 ˇ M. P.: 8 ēC ˇ B. P.: 149 ēC ˇ n20/D: 1,5976 ˇ Flash P.: NO ˇ Vap. press. at 20 ° C 6,6 hPa ˇ
APPLICATIONS: Used in separating mixtures of minerals ˇ Synthesis reagent: Widely-used precursor of dibromocarbene , which is produced on treatment with base . Carbenes of enhanced reactivity may be obtained in the presence of phase transfer catalysts ˇ Using 18-crown-6 as catalyst , at elevated temperatures , potassium carbonate can function as a base ˇ Addition of dibromocarbene to silyl enol ethers , gives the expected adduct , which undergoes ring-opening to give an a-bromoenone ˇ Bromochloroadducts can be obtained in the presence of carbon tetrachloride and ultrasonic irradiation ˇ Reaction of allylic bromides with bromoform and base , leads to displacement of bromine by the trihalomethyl anion
