Commercial carbonaceous materials (Darco KB-G, Norit SX2 and Vulcan XC72) were functionalized with phenyl primary amine using diazonium coupling. The chemical grafting procedure yielded carbon-based basic catalysts, in which the introduced amine group was readily accessible to the reactants. These basic solids were characterized by different technics (elemental analysis, N2 adsorption-desorption, TGA, SEM, FT-IR and XPS). Basic solid Darco-0.5PDA exhibited high activity to the Knoevenagel condensation of furfural and malononitrile under mild experimental conditions (40 °C, Patm).
