Bromochloroiodomethane is a trihalomethane with the chemical formula . This complex organic compound is characterized by having three halogen atoms—bromine, chlorine, and iodine—bonded to a methane backbone. The compound has R and S configurations.
Synthesis It can be prepared by reacting a solution of bromodiiodomethane in carbon tetrachloride with a solution of antimony pentachloride in dichloromethane at 0 °C.
Chemical properties Like other trihalomethanes, it can be deprotonated in situ at low temperatures to give chlorobromoiodomethyl anions. For example, it can react with phenylmercuric chloride in the presence of potassium tert-butoxide to form phenyl(chlorobromoiodomethyl)mercury.
Physical properties The compound forms a pale yellow liquid that is soluble in organic solvents but poorly soluble in water.
Uses The compound is primarily used as a reagent in organic synthesis and as a building block for more complex molecules.
