Dibromofluoromethane is a mixed halomethane.[1] It is soluble in alcohol, acetone, benzene and chloroform. It is prepared from dibromomethane and antimony(III) fluoride.[2]
Applications
[edit]It can be used to prepare bromofluoromethane by reductive debromination with organotin hydride as tributyltin hydride.[3]
Regulations
[edit]Its ozone depletion potential (ODP) is 1.0 and it is included in list of Class I Ozone-Depleting Substances.
