摘要：

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. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
