Dehydrofluorination reactions of fluoroalkanes were catalyzed by nanoscopic aluminum chlorofluoride (ACF, AlClxF3-x, x approximate to 0.05-0.3) in the presence of HSnBu3. Mechanistic studies suggest an initial interaction of ACF with the tin hydride instead of the fluoroalkane.
Dehydrofluorination reactions of fluoroalkanes were catalyzed by the highly Lewis acidic nanoscopic aluminum chlorofluoride (ACF, AlClxF3-x, x approximate to 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 as the capability of ACF to perform C-F bond activation of fluoroalkanes without additives.
