Chlorodifluoroiodomethane is a tetrahalomethane with the chemical formula . This is a halomethane containing two fluorine atoms, one chlorine atom, and one iodine atom attached to the methane backbone.
Synthesis It can be prepared by reacting methyl difluorochloroacetate, LiCl/HMPA, and iodine or iodine monobromide at 90–95 °C, or by reacting silver difluorochloroacetate and iodine at 120–260 °C:
The compound can also be obtained by the inductively coupled plasma (12 MHz) reaction of hexafluoroethane or trifluorochloromethane with iodine. Other methods are also known.
