The solvent-free condensation reaction of various aliphatic aldehydes, cycloalkanones, and benzaldehydes with rhodanines catalyzed by Amberlyst 26 has been reported. The catalyst's efficiency, simple work-up, simple recycling procedure, and high catalyst recyclability without any considerable change of yields several times were found to be interesting. Furthermore, the drastic acceleration of ultrasound
