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:[4]
CClF2COOAg + I2 → CClF2I + CO2 + AgI
The compound can also be obtained by the inductively coupled plasma (12 MHz) reaction of hexafluoroethane or trifluorochloromethane with iodine.[5] Other methods are also known.[6]
