herein is that a new approach to a one-pot two-step conversion of aromatic carboxylic acids/esters to aromaticaldehydes, in which indium(III) iodide effectively catalyzes both the first reductive thioacetalization of carboxylic acids and a subsequent desulfurization of the in-situ formed thioacetal intermediates leading to aldehydes.
