摘要：

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. (C) 2002 Elsevier Science Ltd. All rights reserved.
