A convenient method for synthesis of terpyridines via a cooperative vinylogous anomeric based oxidation.

ABSTRACT: The presented study is the first report of the synthesis of terpyridines in the presence of a nanomagnetic catalyst instead of harmful reagents. Herein, Fe₃O₄@O₂PO₂(CH₂)₂NH₃ ⁺CF₃CO₂ ^- as a retrievable nanocatalyst with magnetic properties was applied for the multi-component reaction between acetylpyridine derivatives (2 or 3 or 4-isomer), aryl aldehydes and ammonium acetate under conventional heating conditions in the absence of any solvent. The derived terpyridines were obtained with acceptable yields and brief reaction times via a cooperative vinylogous anomeric based oxidation route. Fe₃O₄@O₂PO₂(CH₂)₂NH₃ ⁺CF₃CO₂ ^- showed a high capability for recovery and reuse in the mentioned reaction.

Synthesis and application of a bimetallic-MOFs with sulfonic acid tags in preparation of biologically active nicotinonitriles via cooperative vinylogous anomeric-based oxidation.

Project description:Bimetallic-organic frameworks (bimetallic-MOFs) have broad capabilities owing to the synergistic properties of two metals in a single structure. In this regard, we prepared a bimetallic-MOF containing iron (Fe) and nickel (Ni) metals. The prepared bimetallic-MOF was functionalized with sulfonic acid groups via a post-modification method. Thus, a new acidic catalyst with special abilities was prepared. The physicochemical properties of the bimetallic-MOF containing sulfonic acid groups were investigated through FT-IR, SEM, BET/BJH, XRD, EDS, elemental mapping and TGA/DTG analyses. According to the acidic active sites in the structure of the presented catalyst, we investigated the performance of this catalyst in the synthesis of nicotinonitrile derivatives. The structure of the products was also confirmed using melting point, FT-IR, HR-mass, 1H-NMR, and 13C-NMR analyses. Moreover, the antibacterial properties of the synthesized product and MIL-88B(Fe2/Ni)/imidazole/SO3H were investigated, and results showed satisfactory antibacterial properties of these compounds against Gram-positive and Gram-negative bacteria.
