Abstract

Scandium triflate [Sc (OTf) 3] has been found to be an extremely efficient and recyclable catalyst for the addition of ethanethiol, 1, 2-ethanedithiol and 1, 3-propanedithiol to both aromatic and aliphatic aldehydes. In addition, by employing this catalyst, high chemoselective thioacetalization of carbonyl compounds has been achieved.
