Tribromoiodomethane is a tetrahalomethane with the chemical formula CBr3I. This is a halomethane containing three bromine atoms and one iodine atom attached to the methane backbone.
Synthesis The compound can be obtained by reacting carbon tetrabromide and sodium iodide in acetone with a yield of 30%. The remaining products of the reaction are brominated acetone and trace amounts of bromotriiodomethane.
CBr4 + NaI + acetone → CBr3I + CBrI3 + brominated acetone Tribromoiodomethane can also be produced by the reaction of nitrotribromomethane with a small amount of potassium iodide:
CBr3NO2 + KI → CBr3I + KNO2
Uses The compound can be used to introduce tribromomethyl groups into organic compounds.
