Abstract: Copper nanoparticles assembled on carboxymethylcellulose (Cu0NPs@CMC) were successfully synthesized and well characterized by FT-IR, SEM, EDS, TEM, XPS, and ICP-AES. The new prepared nanocatalyst was applied effectively as a heterogen

Highly active and stable magnetic copper catalysts were successfully achieved by magnetic induced St?ber method and subsequent hydrothermal reaction with copper ions in alkaline condition. The high content of Cu2+ as well as the unique structures of hierarchical copper silicate in the as-prepared catalysts endowed their outstanding catalytic performance. Efficient decarboxylative A3-coupling of α-keto acid, amine and alkyne was realized with the low Fe3O4&at;CuSiO3 loading. A range of propargylamines were produced in good to excellent yields under solvent-free condition. Moreover, the catalyst can be easily separated from the final organic product with an external magnet. Also, this kind of catalyst could be recycled up to six times while maintaining its activity.

A novel and efficient microwave-assisted decarboxylative three-component coupling of a 2-oxoacetic acid, an amine, and an alkyne (OA2- coulpling) has been developed. This new multicomponent coupling constitutes an efficient approach for the syn
