Carboxamide functionality grafted entangled Co(ii) framework as a unique hydrogen-bond-donor catalyst in solvent-free tandem deacetalization-Knoevenagel condensation with pore-fitting-mediated size-selectivity

Pore-wall decked carboxamide groups in an entangled bipillar-layer Co( ii ) framework act as unprecedented two-point hydrogen-bonding centres to drive tandem deacetalization-Knoevenagel condensation in a solvent-free and size-selective fashion.
