• Summary:An efficient, recyclable and large-scalable fiber-supported Fe(III) catalytic system verifed in the one-pot
  multicomponent Biginelli reactions, is presented. The fiber catalyst was prepared conveniently from
  commercially available polyacrylonitrile fiber according to a simple two-step procedure by amination
  and chelation in water, and characterized detailedly with ICP analysis, morphology, mechanical
  properties, elemental analysis, FTIR spectroscopy, and SEM during the modification and utilization
  processes. Moreover, the fiber catalyst-mediated reactions showed broad applicability and proceeded
  smoothly to afford a series of substituted 3,4-dihydropyrimidin-2-(1H)-ones/-thiones (yields 81–94%) in
  ethanol under mild conditions. Furthermore, the newly developed fiber catalyst held high strength, good
  flexibility and exhibited excellent stability and recyclability (over 10 cycles), and the procedure was
  operationally concise and effectively amenable to the gram-scale on a simple
  fixed-bed reactor with potential industrialization prospect.
