Bromotriiodomethane is a tetrahalomethane with the chemical formula . This is a halomethane containing one bromine atom and three iodine atoms attached to the methane backbone.
Synthesis Bromotriiodomethane is prepared by the reaction of triiodomethane with sodium hypobromite. It is formed as a trace by-product in the reaction of carbon tetrabromide with sodium iodide in acetone, with bromotriiodomethane being the main product (30%).
Physical properties Bromotriiodomethane forms an unstable solid that releases iodine upon exposure to light. It is soluble in water.
