For first time, in this work, a new, heterogeneous and recyclable catalyst was designed using immobilizing Cu on 2-(5-Aminopyrimidin-2-yl)pyrimidin-5-amine ([CuAPPA·2H2O]n) named metal–organic frameworks (MOFs). This catalyst was used for the synthesis of biaryl derivatives by Suzuki reaction. Suzuki reaction performed with mixing of the aryl halides with arylboronic acids in the DMF solvent conditions. Also, the prepared catalyst was characterized with different analytical techniques such as FT-IR, XRD, SEM, EDX, BET and ICP-AES analysis. [CuAPPA·2H2O]n catalyst displayed good to excellent yields catalytic efficiency for Suzuki reaction in comparison with to other catalysts. Also, the recoverability and reusability related to this catalyst was checked by a simple filtration with reserving its activity even after several cycles.

In this work, it was designed and prepared an efficient nanocatalyst Pd based on [2,2'- bipyridin]-4-amine functionalized nano cellulose (Pd?BPA?CNC) and then characterized by FT-IR, XRD, ICP-AES, EDX, SEM, TEM and TGA techniques. The catalytic activity of the nanocatalyst was investigated through one-pot synthesis of biaryl derivatives from the reaction of aryl halides with arylboronic acids in DMSO solvent conditions. This Simple and mild procedure displayed excellent recyclability and provided cleaner conversion in a short reaction time. All of these advantages make the protocol feasible and economical attractive for researchers.
Preparation and characterization of Cu supported on 2-(1H-benzo[d]imidazol-2-yl)aniline-functionalized Fe3O4 nanoparticles as a novel magnetic catalyst for Ullmann and Suzuki cross-coupling reactions

Copper supported on 2-(1H-benzo[d]imidazol-2-yl)aniline (BIA)-functionalized Fe3O4 nanoparticles (Cu-BIA-Si-Fe3O4) as a novel magnetic catalyst was designed and used for the synthesis of new products via Ullmann and Suzuki cross-coupling reactions. The Ullmann reaction was performed by mixing arylboronic acid with aniline derivatives in dimethylsulfoxide solvent. Also, diaryls were synthesized via Suzuki C–C reactions between aryl halides and phenylboronic acid in the same solvent. The prepared materials and catalyst were characterized with various analytical techniques. The Cu-BIA-Si-Fe3O4 catalyst demonstrated catalytic efficiency with good to excellent yields for both types of reactions in comparison with commercial palladium catalysts. Also, the catalyst could be recovered by a simple filtration and retained its activity even after several cycles.
