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. The carbon atom has a lone-pair and a single unpaired (radical) electron in the ground state. Ground-state fluoromethylidyne radicals can be produced by the ultraviolet photodissociation of dibromodifluoromethane at 248 nanometer wavelength. It readily and irreversibly dimerises to difluoroacetylene, also known as difluoroethyne, perfluoroacetylene, or di- or perfluoroethylyne. Under certain conditions it can hexamerise to hexafluorobenzene. (en) Le fluorométhylidyne est une espèce chimique de formule CF. Il s'agit d'un radical métastable contenant un atome de carbone très réactif lié à un atome de fluor. L'atome de carbone possède un doublet non liant et un électron célibataire non apparié à l'état fondamental. De telles espèces chimiques peuvent être produites à l'état fondamental par photolyse ultraviolette du dibromodifluorométhane à 248 nm de longueur d'onde. Il dimérise facilement et irréversiblement en difluoroacétylène et peut, sous certaines conditions, polymériser en hexafluorobenzène. Le cation fluorométhylidynium CF+ a été détecté dans le milieu interstellaire. (fr) |
