  Kinetic studies of the reactions CF3O2+Cl and CF3O2+NO were performed at room temperature in the gas phase using the discharge flow mass spectrometric technique (DFMS). The reactions were investigated under pseudo-first-order conditions with Cl or NO in large excess with respect to the CF3O2 radicals. The rate constant for the reaction CF3O2+NO was measured at 298 K and the value of (1.6±0.3)×10-11 cm3 molecule-1 s-1 is in very good agreement with all previous values. For the reaction CF3O2+Cl, we obtain a rate constant at 298 K of (4.2±0.8)×10-11 cm3 molecule-1 s-1 in excellent agreement with the only published value. Product analysis shows that this reaction occurs via the major reaction pathway CF3O2+Cl→CF3O+ClO at room temperature. In addition, an abinitio theoretical study was performed to gain insights on the different postulated reaction pathways. There is a significant disagreement between experimental and abinitio values recommended for the formation enthalpies of CF2O, CF3O and related molecules produced in this system. Consequently, we provide self-consistent values of enthalpies based on isodesmic reactions for the CF3O2+Cl reaction system using the G2, G2(MP2) and CBS-Q methods. These values are also compared with BAC-MP4 heats of formation calculated in this work.

  利用放电流质谱技术（DFMS）在室温下对气相中的 CF3O2+Cl 和 CF3O2+NO 反应进行了动力学研究。在 Cl 或 NO 相对于 CF3O2 自由基大量过量的伪一阶条件下对反应进行了研究。在 298 K 条件下测量了 CF3O2+NO 反应的速率常数，其值为 (1.6±0.3)×10-11 cm3 molecule-1 s-1，与之前的所有值非常吻合。对于 CF3O2+Cl 反应，我们在 298 K 时得到的速率常数为 (4.2±0.8)×10-11 cm3 molecule-1 s-1，与唯一公布的数值非常一致。产物分析表明，该反应在室温下通过主要反应途径 CF3O2+Cl→CF3O+ClO 发生。此外，还进行了一项非比寻常的理论研究，以深入了解不同的假定反应途径。对于该体系中产生的 CF2O、CF3O 和相关分子的形成焓，实验值和非比邻推荐值之间存在很大分歧。因此，我们使用 G2、G2(MP2) 和 CBS-Q 方法，根据 CF3O2+Cl 反应体系的等效反应提供了自洽的焓值。这些值还与本研究中计算的 BAC-MP4 形成热进行了比较。

  The reaction of bis(fluoroformyl) peroxide 1 with F2 in the presence of CsHF2 of KHF2 produces FOCF2OOC(O)F 2 in 60% yield. The previously known FOCF2OOCF2OF is also obtained as a byproduct along with small amounts of the new compounds FOCF2OOC(O)OOC(O)F 3 and FOCF2OOC(O)OOCF2OF 4. Hydrolysis of 2 affords either FOCF2OOC(O)OOCF2OF 4 or FOCF2OOH 5 in low yield, depending on the reaction conditions.

  在KHF 2的CsHF 2存在下，双（氟甲酰基）过氧化物1与F 2的反应产生FOCF 2 OOC（O）F 2，产率为60％。还与少量新化合物FOCF 2 OOC（O）OOC（O）F 3和FOCF 2 OOC（O）OOCF 2 OF 4一起作为副产物获得了先前已知的FOCF 2 OOCF 2 OF 。2的水解产生FOCF 2 OOC（O）OOCF 2 OF 4或FOCF 2 OOH 5取决于反应条件，收率低。过氧化物的氟化3 - 5提供高收率的相应的氟氧基化合物，并提供结构的进一步证明。
