摘要：
Moisture stable dialkylimidazolium salts act as heterogeneous and homogeneous Lewis acid catalysts in the Diels-Alder reaction of both crotonaldehyde and methacrolein with cyclopentadiene at low temperatures. The heterogeneous system allows the catalyst to be efficiently recycled. (C) 1997 Elsevier Science Ltd.
