摘要
A new proline-functionalized fiber catalyst was employed for the first time to catalyze the Knoevenagel condensation reactions between aromatic aldehydes and ethyl cyanoacetate or malononitrile. This fiber catalyst exhibits a high efficiency （0.5-2 tool% of catalyst with yields of 90%-99%） and excellent reusability （up to 20 times） without the need for additional treatments.
