摘要：
A novel organocatalyst of pyrrolidine amide based on room temperature ionic liquid (RTIL) has been developed to perform Claisen-Schmidt reaction with acetone or cyclic ketone and various aromatic aldehydes at room temperature under free-solvent condition. The (E)-alpha,beta-unsaturated ketone products were obtained in good yields. The ionic liquid supported pyrrolidine amide catalyst can be readily recovered and reused successfully without any significant loss of catalytic activity. (c) 2007 Published by Elsevier B.V.
