摘要：

Immobilized scandium triflate [Sc(OTf)(3)] in ionic liquids has been found to be an extremely efficient and recyclable catalyst for the thioacetalization and transthioacetalization of both aromatic and aliphatic aldehydes. Significant rate acceleration and chemoselectivity was achieved by employing this catalytic system. (C) 2003 Elsevier Science Ltd. All rights reserved.
