Bromine oxide trifluoride

Bromine oxide trifluoride, p3BrO, is made by reaction of K[p4BrO] with a weak Lewis acid ... 

Bromine oxide trifluoride can be prepared by the reaction of KBrOF4 with HF. It decomposes slowly at room temperature to give O2 and BrFs.

SAFETY PROFILE An inhalation hazard. Mildly toxic by an unspecified route. An experimental teratogen. Experimental reproductive effects. A skin and eye irritant. Flammable in the form of dust when exposed to flame. The powdered metal may ignite on contact with air or oxidants (e.g., bromine pentafluoride, bromine, chlorine trifluoride, potassium perchlorate, potassium dichromate, nitryl fluoride, fluorine, oxygen difluoride, iodine pentafluoride, hydrogen sulfide, sodium peroxide, lead(IV) oxide). 

Safety. Magnesium oxide (fume) has a permissible exposure limit (PEL) (134) (8 hours, TWA), of 10 mg/m total dust and 5 mg/m respirable fraction. Tumorigenic data (intravenous in hamsters) show a TD q of 480 mg/kg after 30 weeks of intermittent dosing (135), and toxicity effects data show a TC q of 400 mg/m for inhalation in humans (136). Magnesium oxide is compatible with most chemicals exceptions are strong acids, bromine pentafluoride, chlorine trifluoride, interhalogens, strong oxidizers, and phosphorous pentachloride. 

Thallium (ITT) fluoride has been prepared by the action of fluorine or bromine trifluoride on thaUium(III) oxide at 300°C. It is stable to ca 500°C but is extremely sensitive to moisture. Thallium (ITT) chloride can be obtained readily as the tetrahydrate [13453-33-3] by passing chlorine through a boiling suspension of HCl in water. It can be dehydrated with thionyl chloride. Thallium (ITT) bromide tetrahydrate [13453-29-7] is prepared similarly, whereas the iodide prepared in this manner is thaUium(I) triiodide [13453-37-7] H" F2-... 

The time-weighted, 8-h average limit for exposure to bromine pentafluoride is 0.1 ppm (67). Materials of constmction suitable for use with the bromine fluorides include nickel. Monel metal, or Teflon. For shipping, bromine trifluoride and pentafluoride are classified as oxidizers under DOT regulations. The trifluoride also requires a poison label.

The above book [1] deals, in 26 chapters in 5 sections, with theoretical and practical aspects of the use and safe handling of powerful oxidants and their complementary reactive fuels. Materials include nitrogen pentaoxide, perfluoroam-monium ion and salts, nitronium tetrafluoroborate, hydrazinium mono- and diperchlorates, nitronium perchlorate, tricyanomethyl compounds, difluoramine and its alkyl derivatives, oxygen difluoride, chlorine trifluoride, dinitrogen tetraoxide, bromine trifluoride nitrogen fluorides, and liquid ozone-fluorine system. 

Bromine trifluoride is a highly reactive compound. It ignites or explodes in contact with a wide array of substances including water, finely divided metals, metal oxides and salts and organics. See Bromine Pentafluoride. 

The products ArCF2SMe are assumed to be precursors of ArCF3. Indeed, l-(tri-fluoromethyl)naphthalene is obtained in 83% yield by the reaction of l-[difluoro(methylsul-fanyl)mcthyl]naphthalene with tetrabutylammonium dihydrogen trifluoride/ l,3-dibromo-5,5-dimethylhydantoin. It should be noted that under the oxidative desulfurization conditions the electron-rich aromatic compounds can undergo ring bromination. 

Chlorine trifluoride does not oxidize bromine atoms in perfluorobromobenzene and peril uoro- 1 - bromopropa ne.
