Dehydrofluorination reactions of fluoroalkanes were catalyzed by the highly Lewis acidic nanoscopic aluminum chlorofluoride (ACF, AlClxF3-x, x ≈ 0.05–0.3) in the presence of HSnBu3 as hydrogen source. Mechanistic studies suggest an initial interaction of ACF with the tin hydride instead of the fluoroalkane. MAS NMR studies provided information on the interaction of HSnBu3 with the ACF surface as well
在 HSnBu 3作为氢源的情况下,氟代烷烃的脱氟化氢反应由高路易斯酸性纳米级氯氟化铝 (ACF, AlCl x F 3- x , x ≈ 0.05–0.3) 催化。机理研究表明 ACF 与氢化锡而不是氟烷的初始相互作用。MAS NMR 研究提供了有关 HSnBu 3与 ACF 表面的相互作用以及 ACF 在没有添加剂的情况下对氟代烷烃进行 C-F 键活化的能力的信息。
