Chemical compound
Fluoromethylidyne is not a stable chemical species but a metastable radical containing one highly reactive carbon atom bound to one fluorine atom with the formula CF.[1] The carbon atom has a lone-pair and a single unpaired (radical) electron in the ground state.[2]
Ground-state fluoromethylidyne radicals can be produced by the ultraviolet photodissociation of dibromodifluoromethane at 248 nanometer wavelength.[3]
It readily and irreversibly dimerises to difluoroacetylene, also known as difluoroethyne, perfluoroacetylene, or di- or perfluoroethylyne. Under certain conditions it can hexamerise to hexafluorobenzene.
