Hydrogen, reaction with bromine carbon dioxide

The above procedure was subject to various modifications. The bromine could be removed by aeration with air, carbon dioxide, hydrogen sulfide or sulfur dioxide. The hydrogen bromide formed in the reaction... 

EXPLOSION and FIRE CONCERNS a highly flammable liquid NFPA rating Health 2, Flammability 2, Reactivity 1 vapors form explosive mixtures with air, explosive reactions with bromine pentafluoride, chromium trioxide, hydrogen peroxide, potassium permanganate, sodium peroxide ignites on contact with pot issium-tert-butoxide incompatible or reacts violently with acetaldehyde, acetic anhydride, chromic acid, nitric acid, ammonium nitrate, chlorine trifluoride, (nitric acid + acetone), perchloric acid, potassium hydroxide, sodium hydroxide, xylene use water spray, dry chemical, foam, or carbon dioxide for firefighting purposes. 

Alkanes are fuels they burn in air if ignited. Complete combustion gives carbon dioxide and water less complete combustion gives carbon monoxide or other less oxidized forms of carbon. Alkanes react with halogens (chlorine or bromine) in a reaction initiated by heat or light. One or more hydrogens can be replaced by halogens. This substitution reaction occurs by a free-radical chain mechanism. 

Since the excess trimethylsilyl bromide was difficult to remove, an alternative sequence was investigated (Scheme 10). After bromination of the silyl enol ether, the reaction mixture was poured into water to hydrolyze both the trimethylsilyl bromide and the anhydride. On heating this bromoacid as before, an unexpected compound was formed. This can be rationalized as follows The reaction proceeds from the enol form, and the mechanism is formally 1,5 elimination of hydrogen bromide with concomitant loss of carbon dioxide. The second decarboxylation is analogous to the one seen earlier, and would be expected of the a,8-unsaturated ketone.
