Hydrodechlorination of Monochlorodifluoromethane

For hydrodehalogenation reactions in halocarbons with just one kind of halogen in it, e.g. pure fluorocarbons or chlorocarbons, respectively, these new highly Lewis acidic noble metal/MFx-catalysts should therefore be excellent candidates because dismutation as an undesired side reaction can be disregarded. Thus, starting with pure CHCI3 complete hydrodechlorination was observed over Pd /AIFa at 423 K whereas the Pd /C-catalyst gave only around 70% conversion under the same conditions, with remarkable amounts of incompletely converted mono and dichloromethanes.
