摘要：Condensation of aromatic aldehydes with cyclopentanone and cyclohexanone using amino-functionalized ionic liquid, 1-aminoethyl-3-methyl tetrafluoroborate as solvent and catalyst was successfully performed for preparation of alpha,alpha'-bis(substituted benzylidene)cycloalkanones. The catalyst can be recovered and reused for at least three times without apparently lose of activity. The process is simple, environmentally benign and proceeds in excellent yields.
