One‐Pot Substitution of Aliphatic Alcohols Mediated by Sulfuryl Fluoride. Catalytic tests on methanol, ethanol, and 1- and 2-propanol at 400 °C supported the proposed relative selectivity; besides, the recorded alcohol total conversions and product yields agree well with what was proposed by the DFT reaction profiles, thus demonstrating the predictive capability of the chosen electronic structure approach.

SO In all cases the Ref. Computing the relative reaction barriers with all electron DFT and split-valence basis sets for a panel of 11 alcohols suggested dehydrogenation to be the most active process catalysed by gallia for both primary and secondary alcohols despite its fundamentally acidic behaviour, which was previously suggested to foster dehydration. 2
