The greenhouse gas SFCF was photochemically activated with SIMes (1,3-Bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene) to give 1,3-dimesityl-2,2-difluoroimidazolidine (SIMesF), and 1,3-dimesitylimidazolidine-2-sulfide, as well as the trifluoromethylated carbene derivative 1,3-dimesityl-2-fluoro-2-trifluoromethylimidazolidine. CF radicals, as well as SF, serve presumably as intermediates of the conversions. In addition, the photochemical activation of SFCF was performed in the presence of triphenylphosphine. The formation of triphenyldifluorophosphorane and triphenylphosphine sulfide was observed.
温室气体SFCF用SIMes（1,3-双（2,4,6-三甲基苯基）-4,5-二氢咪唑-2-亚基）进行光化学活化，得到1,3-二甲基-2,2-二氟咪唑烷（SIMesF）、1,3-二甲基咪唑烷-2-硫化物以及三氟甲基化卡宾衍生物1,3-二甲基-2-氟-2-三氟甲基咪唑烷。CF自由基以及SF可能是这些转化过程的中间体。此外，SFCF的光化学活化是在三苯基膦存在下进行的。观察到了二氟三苯基膦和三苯基膦硫化物的形成。
