| Abstract: | Using NH2SO3H as catalyst, a series of α,α'-bis(substituted benzylidene)cycloalkanone derivatives were synthesized by cross aldol condensations of cycloalkanones with aldehydes under solvent-free conditions and ultrasound irradiation in 15～45 min with 76%～92% yields. Compared with traditional method, this method was more convenient and environmental friendly. |
