Commercial CaO was modified simply with benzyl bromide. The modified CaO had good water resistance, and characterization by FTIR and TG revealed the modifier was chemically bonded to the CaO surface. Commercial CaO and CaO modified with benzyl bromide were investigated as catalysts for the Henry reaction between benzaldehyde and nitromethane. It was found that the catalytic activity of the modified CaO was greatly improved, with high conversion of benzaldehyde to the (E)-phenyl nitroolefin and 1-phenyl-2-nitroethanol, and with different selectivity from commercial CaO. The effect of modification and reaction conditions on yield, selectivity, and mechanism were studied thoroughly.

Ethylenediamine moieties with different amounts were incorporated into the metal-organic framework MIL-101 to prepare the amino-functionalized MIL-101 materials, which were used as heterogeneous catalysts in the one-pot synthesis of nitroalkenes via the Henry reaction. Various reaction conditions were optimized. Under the optimized conditions, the selectivity towards nitroalkenes is extremely high in combination with nearly complete conversion of the reactant nitroalkanes. The amino-functionalized MIL-101 behaves as a true heterogeneous catalyst, can be easily recovered by filtration, and can be reused at least twice without significant loss of its catalytic performance.
