Synthesis of Highly Deactivated Polyhalogenated Aromatic Compounds

The barium fluorobromate(III) was obtained as the product of interaction between barium fluoride and bromine(III) trifluoride. The heat of formation of Ba(BrF4)2 was found by isothermal calorimetry method. By the TG/DT analysis the thermal stability of Ba(BrF4)2 was researched. It was found that this compound is mostly stable in the atmosphere or argon up to 250 °C. It was shown that bromine trifluoride and its derive compounds with alkali and alkali-earth metals fluorides can be applied like a highly-active brominating agent in case of production of various composite materials based on polyhalogenated aromatics.
