  • Reactions of Fluoroalkenes with an Aluminium(I) Complex
    作者:Clare Bakewell、Andrew J. P. White、Mark R. Crimmin

    and 2) stepwise formation and decomposition of a metallocyclopropane intermediate occurs with inversion of alkene stereochemistry. As part of this mechanistic analysis, we have isolated the first aluminium metallocyclopropane complex from oxidative addition of an alkene to AlI. Remarkably this reaction is reversible and reductive elimination of the alkene occurs at higher temperature reforming AlI.
    一系列与工业相关的氟代烯烃与单体Al I络合物反应。这些反应破坏了强力的sp 2和sp 3 C-F键,并导致形成各种有机铝化合物。机理研究表明,可能有两种作用机理:1)C-F键与Al I的直接氧化加成发生在保留烯烃立体化学的情况下; 2)金属环丙烷中间体的逐步形成和分解发生在烯烃立体化学的逆转过程中。作为该机理分析的一部分,我们从将烯烃氧化加成到铝I中分离出了第一个铝金属环丙烷络合物。显着地,该反应是可逆的,并且在较高温度下重整Al I时烯烃的还原消除。此外,在某些情况下,有机铝产品易于消除β-氟化物,从而产生双CF活化途径。

    3,3,4,4,5,5-hexafluorocyclopentene (6FE), 1,3,3,4,4,5,5-heptafluorocyclopentene (7FE) and octafluorocyclopentene (8FE) are considered as new generation of potential chlorofluorocarbons substitutes. To investigate the thermostabilities, tubular furnace experiments were designed over temperature range of 500-850℃. The results show that 6FE, 7FE and 8FE are all stable below 650 ℃, thus have good stabilities
    3,3,4,4,5,5-六氟环戊烯(6FE),1,3,3,4,4,5,5-七氟环戊烯(7FE)和八氟环戊烯(8FE)被视为新一代潜在的氯氟烃替代物。为了研究热稳定性,设计了在500-850℃温度范围内的管式炉实验。结果表明,6FE,7FE和8FE在650℃以下均稳定,因此在一般贮存和实际使用条件下具有良好的稳定性。此外,考虑到较短的大气寿命(数月),较低的全球变暖潜能值(GWP,低于119)和零臭氧消耗潜能值(ODP),这些化合物似乎对气候变化影响不大。
