Catalytic CO2 fixation over a high-throughput synthesized copper terephthalate metal-organic framework

Sulfonated magnetic sugarcane bagasse as an efficient natural polymer-based catalyst for the synthesis of nitrogen-containing heterocyclic rings in water

A new species of catalysts that are prepared from biocompatible materials is demonstrated. Sulfonated magnetic sugarcane bagasse has been synthesized as a novel biodegradable and robust heterogeneous catalyst for organic transformations. The catalyst was characterized by different techniques. Next, the efficiency of this acid catalyst was examined with multi-component reactions for the synthesis of some biologically active scaffolds of heterocyclic organic compounds such 2,3-dihydroquinazolin-4(1H)-ones and pyrido[2,3-d]pyrimidin-4-one derivatives. A wide range of these heterocycles was synthesized with excellent yields in short reaction times under green conditions. In all cases, sulfonated magnetic sugarcane bagasse could be simply collected using an external magnet and reused for several runs without any significant loss of catalytic activity.

In situ cleavage and rearrangement synthesis of an easy-to-obtain and highly stable Cu(ii)-based MOF for efficient heterogeneous catalysis of carbon dioxide conversion

A Cu(ii)-based MOF has been synthesized by the in situ cleavage and rearrangement solvothermal synthesis. This material exhibits highly stabilities and CO2 adsorption ability to catalyze cycloaddition of CO2 with epoxides efficiently.
