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.

Key words: aromatic aldehyde, ultrasound irradiation, cycloalkanone, solvent-free, aldol condensation
