Tribromochloromethane is a tetrahalomethane with the chemical formula CBr3Cl. This is an organic compound containing three bromine atoms and one chlorine atom attached to the methane backbone.
Synthesis Tribromochloromethane can be prepared by the reflux reaction of carbon tetrachloride and aluminum tribromide or by the reaction of chlorocyclohexane and carbon tetrabromide in presence of ferric bromide.
CCl4 + AlBr3 ⟶ CBr3Cl + AlCl3 CBr4 + C6H11Cl ⟶ CBr3Cl + C6H11Br Also, dibromoformaldehyde oxime reacts with aqueous mercury dichloride solution, and then reacts with bromine and sodium acetate to obtain dibromochloronitrosomethane, which can then be refluxed with bromine to obtain tribromochloromethane.
Chemical properties Tribromochloromethane reacts with concentrated sulfuric acid to produce carbonyl bromide chloride:
CBr3Cl + H2SO4 → COBrCl + 2HBr + SO3
