Ionic liquid coated sulfonic acid functionalized amorphous carbon/silica composites derived from a starch-glucose mixture were developed and their catalytic activities were evaluated for Knoevenagel condensation, reductive amination of aldehydes and ketones, and for Michael addition of indole to α,β-unsaturated ketones in aqueous medium. The catalyst prepared from starch-glucose mixture (3:1) [CSC-Star-Glu-IL2] showed the highest activity in water. The catalysts were characterized by FTIR, TGA, elemental analysis, and the most active was further characterized by XRD, SEM and TEM.

Catalytic amounts of sodium carbonate (Na2CO3) catalyze the condensation of aromatic aldehydes with active methylene compounds to afford arylmethylidene products under the grindstone method. The reactions go to completion within 1-5 min at 26°C and give products in excellent yield.
