The majority of binary chalcogen fluorides are fiercely reactive and extremely difficult to handle. Here, we show that access to crystalline donor-acceptor complexes between chalcogen difluorides (sulfur, selenium) and tetrafluorides (selenium, tellurium) with the N-heterocyclic carbene (NHC) 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) is possible conveniently and safely without the need to generate the highly unstable EF (E=S, Se) or the very toxic and corrosive SeF .
大多数二元硫属元素氟化物具有极强的反应性，极难处理。在此，我们表明，通过氮杂环卡宾（NHC）1,3-双（2,6-二异丙基苯基）咪唑-2-亚基（IPr），可以方便、安全地获得硫属元素二氟化物（硫、硒）与四氟化物（硒、碲）之间的晶体供体-受体配合物，而无需生成极不稳定的EF（E = S、Se）或剧毒且腐蚀性强的SeF 。
