Phosphorus Trifluorodibromide, PF3Br2
Phosphorus Trifluorodibromide, PF3Br2, was first produced by passing bromine into phosphorus trifluoride cooled by a freezing mixture. It is a pale brown fuming liquid which freezes to a yellow solid at -20° C. and decomposes at ordinary temperatures in a similar manner to the dichloride:—
5PF3Br2 = 3PF5 + 2PBr5 On complete hydrolysis it gives H3PO4, HF and HBr. The corresponding diiodide, PF3I2, is probably formed when the trifluoride is absorbed by iodine. It is a yellowish-red solid. |
