Chlorodefluorination of Fluoromethanes and Fluoroolefins at a Lewis Acidic Aluminum Fluoride
Xinzi Pan, María Talavera, Gudrun Scholz, Thomas Braun
Abstract
Abstract Chlorodefluorination reactions of fluoromethanes and fluoroolefins catalysed by the highly Lewis acidic nanoscopic aluminum chlorofluoride (ACF, AlCl x F 3− x , x ≈0.05–0.3) in the presence of ClSiEt 3 were studied. Both fluoromethanes and fluoroolefins convert under mild reaction conditions by fluorine‐chlorine exchange steps into chlorinated fluoro derivatives. MAS NMR studies provided information on the interaction of silanes and hexafluoropropene with the ACF surface.
