Neue Sauerstofffluoride: O₂F₂ und OF

Does Oxygen Feature Chalcogen Bonding?

“…For instance, fluorine nitrate (FONO 2 ) was synthesized by Cady [58] and theoretically explored by others [59]. The compounds such as perchloryl fluoride (FClO 3 , b) [60], bis(fluoroxy)perfluoromethane (CF 4 O 2 , d) [61], difluorochloromethyl hypofluorite (CF 2 ClOF, f) [62], trifluoromethyl peroxynitrate (CF 4 NO 4 , i) [63], fluorooxy hypofluorite (O 2 F 2 , k) [64], and others have analogous chemical significance [65]. Trifluoroacetic acid (CF 3 OF, e) is the anionic ion-pairing reagent of choice for peptide separations by reversed-phase high-performance liquid chromatography [66].…”

Low-temperature radiation chemistry. I. Preparation of oxygen fluorides and dioxygenyl tetrafluoroborate

“…In most experiments the amount of reaction mixture prepared for irradiation was 28 mmoles; this was condensed at 77°K into a preevacuated reaction vessel, where it occupied a volume of about 1 ml. The vessel was then transferred to a specially designed stainless steel dewar flask19 filled with liquid nitrogen.…”

The Oxygen Fluorides

“…Some ozone also is formed. The other methods reported in the literature (15,69,76) were shown to be inefficient.…”

“…A. PREPARATION At the present time, dioxygen difluoride is prepared directly from the elements, essentially by the principle described by Ruff and Menzel (76) and by Aoyama and Sakuraba (3, 4). The 1:1 gaseous mixture of fluorine and oxygen is prepared in the perfluorinated stainless steel cylinder.…”
