Difluoroiodomethane is a tetrahalomethane with the chemical formula CHF2I.[3][4] This is a halomethane containing two fluorine atoms and one iodine atom attached to methane backbone.[5][6]

Synthesis

[edit]

The compound can be obtained by the action of mercury(I) fluoride on iodoform:[7]

CHI3 + Hg2F2 → CHF2I + Hg2I↓

Phisical properties

[edit]

The compound forms colorless to almost colorless clear liquid. It is flammable and irritating to the eyes, respiratory tract, and skin.[8]
