Carbonylation of propane in HF-SbF5 (5:1 molar ratio) superacid in the presence of carbon tetrachloride (or chloroform) at -30 deg C yields exclusively the isobutyryl ion (isopropyloxocarbenium ion), analysis of the gaseous fluorocarbons generated as side products showing both hydride abstraction by CCl3+ (or CHCl2+) and Cl/F exchange on the tri- and di-chloromethane formed; in the absence of CCl4 (or(CHCl3) no reaction takes place under the same experimental conditions.
