Abstract

Various types of carbonyl compound can be efficiently and chemoselectively converted to their corresponding dithioacetals in the presence of catalytic amounts of lithium triflate under solvent-free conditions. Due to the neutrality of the reaction medium, this method is especially useful for acid sensitive substrates.
