  Reactions of Atmospheric Ions with Selected Hydrofluorocarbons

  摘要：

  Selected atmospheric ions have been studied for reactivity with the hydrofluorocarbons (HFC's) CF3CH2F, CF3CHFCF3, and CF3CHFCHF2 and with CHBrF2; the reactant ions chosen for study are O+, O-2(+), O-, O-2(-), H3O+, H3O+. H2O, H3O+.(H3O)(2), NO3-, and NO3-. HNO3. Rate constants and product branching fractions for these ion-molecule reactions were measured using a selected ion flow tube (SIFT) instrument operated at 300 K. The ions O+ and O- reacted at the collisional rates, forming a number of ionic products in most cases. Most of the other reactions studied were found to be inefficient. The ions H3O+ and NO3- reacted inefficiently by association in all cases. The solvated ions H3O+. H2O, H3O+.(H2O)(2), and NO3-. HNO3, which are representative of the abundant ionic species in the lower atmosphere, were unreactive with the compounds investigated; we conclude from this that atmospheric ion chemistry is not a significant sink for these HFC's. The observation of proton transfer from CF3CHFCF3 and CF3CHFCHF2 to O- allows a lower bound to the gas-phase acidities of these HFC's to be assigned: Delta H-acid(CF3CHFCF3) and Delta H-acid(CF3CHFCHF2) < 1599 kJ mol(-1).

  Mild and Selective Oxygenation of Sulfides to Sulfoxides and Sulfones by Perfluoro-cis-2,3-dialkyloxaziridines

  摘要：

  Sulfides are oxidized to sulfoxides by stoichiometric amounts of perfluoro-cis-2,3-dialkyloxaziridines 2. The reactions proceed at -40 degrees C with nearly complete selectivity and very good yields. Sulfoxides are also oxidized easily by 2 under mild conditions to corresponding sulfones. The oxidation of some bioactive sulfides (promazine, albendazole, biotin, and others) is also reported.
