摘要：
Fe3O4@FSM-16-SO3H was prepared as new magnetically recoverable catalyst and characterized by SEM, BET, XRD, EDS, VSM and FT-IR techniques. The catalytic activity was investigated in the reaction of various aldehydes, ethyl cyanoacetate, dimedone and ammonium acetate for the preparation of Polyhydroquinolines in one pot. This protocol suggests benefits in terms of higher yields and short reaction time. In addition, the catalyst could be separated using an external magnet and is reusable many times without significant loss of activity.
