Acid–Base Cooperative Catalysis over Mesoporous Nitrogen‐Rich Carbon

WOx nanoclusters (2–3 nm) embedded on a mesoporous nitrogen‐rich carbon material were synthesized by using novel methodology. This material was very effectively capitalized as a new carbon‐based acid–base cooperative catalyst for sequential acetal hydrolysis and Knoevenagel condensation reactions. The protocol was also explored for the nitroaldol condensation reaction.
