  Highly efficient and chemoselective method for the thioacetalization of aldehydes and transthioacetalization of acetals and acylals catalyzed by H2SO4-silica under solvent-free conditions

  摘要：

  Chemoselective and efficient thioacetalization of a variety of aldehydes was achieved in excellent yields at room temperature using 1,2-ethanedithiol in the presence of catalytic amounts of H2SO4-silica. Thioacetals were also prepared by transthioacetalization of acylals and acetals under similar conditions.

  A straightforward and highly efficient procedure for the thioacetalization of a variety of aldehydes and transthioacetalization of acylals and acetals in good to excellent yields using catalytic amounts of sulfonated polyanthracene (S-PAT) is reported. The reactions were carried out in the presence of 1,2-ethanedithiol and 1,3-propanedithiole at room temperature under solvent-free conditions. Thioacetals were also prepared by the reaction of aromatic ketone and dithiole using S-PAT under reflux conditions in H2O as green solvent.
