The Knoevenagel condensation between aromatic aldehydes and malononitrile, ethyl cyanoacetate or malonic acid with hydroxyapatite supported caesium carbonate in water is described. HAP-Cs₂CO₃ was found to be a highly active, stable and recyclable catalyst under the reaction conditions.

The first ultrasound-promoted multicomponent synthesis of pyridazinones and phthalazinones from arenes, cyclic anhydrides and ArNHNH(2) in the presence of an efficient recyclable catalyst, [bmim]Br/AlCl(3), in high yield and short reaction time is reported.

A novel gold nanoparticle supported periodic mesoporous organosilica with alkylimidazolium framework, Au@PMO-IL, was shown to be a highly active and recyclable catalyst for three-component coupling reaction of aldehyde, alkyne and amine to give the corresponding propargylamine.

An efficient amide synthesis by atmospheric pressure aminocarbonylation using palladium nanoparticles supported on MOF-5 is reported. Interestingly, only 0.5 wt% palladium loading was required to achieve high yields. The catalyst is recyclable and offers negligible palladium leaching.

We demonstrated an unprecedented example of Ullmann homocoupling reaction of aryl iodides over a novel recyclable gold catalyst comprising Au nanoparticles supported on a bifunctional periodic mesoporous organosilica (Au@PMO).

A new recyclable rhodium catalyst was synthesized by a simple procedure from readily available reagents, which showed high activities in the hydrogenation of various arenes under 1 atm H2 at room temperature.

In this article, chitosan copper oxide nanocomposite was synthesized by the solution casting method under microwave irradiation. The irradiated at 300 watt for 3 min optimal irradiation conditions. By suppressing particle agglomeration, matrix successfully used as a metal stabilizer. goal of research to create, characterize, and test catalytic potency these hybrid nanocomposites in number well-...

Several novel palladium triphosphine complexes have been synthesized and tested as recyclable catalysts for the methoxylation of alkynes into acetals in ionic liquids. A complete conversion of phenylacetylene was achieved with only 0.2% of [Pd(Triphos)NCMe][(PF6)2] in a methanol/[BMIM][BF4] mixture. We discovered that the addition of an ionic liquid to methanol allowed not only to increase the ...
