Abstract
The bis(4-methoxyphenyl)telluroxide(BMPTO) catalyzed reaction of cyclopentanone or cyclohexanone with aldehydes brought about the cross-aldol condensation to give the corresponding 2, 5-bis(substituted benzylidene) cyclopentanones or 2, 6-bis(substituted benzylidene)cyclohexanones in high yield under microwave irradiation in mild conditions. The reaction needs only 5-10 min.Keywords
