TL;DR: A series of new fiber catalysts has been synthesized by aminating a commercially available polyacrylonitrile fiber with polyamines such as diethylenetriamine and triethylenetetramine as discussed by the authors.

TL;DR: In this paper, a new fiber catalyst for Knoevenagel condensation has been prepared by aminating a commercially available polyacrylonitrile fiber with N,N-dimethyl-1,3-propanediamine.

TL;DR: In this article, 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.

TL;DR: In this article, a dual colorimetric fiber based on two acid base indicators was synthesized by first aminating commercially available polyacrylonitrile fiber with tetraethylenepentamine and then covalently immobilizing ethyl orange moieties through an alkylation reaction and a diazo coupling reaction; finally, the fiber was grafted with phenolphthalein using a Mannich reaction.

TL;DR: In this article, a series of fiber catalysts was proposed to promote the condensation of a wide range of aromatic aldehydes with active methylene compounds. But their performance was limited.
