Removal of the Cd(II), Ni(II), and Pb(II) ions via their complexation with the uric acid-based adsorbent and use of the corresponding Cd-complex for the synthesis of tetrazoles

The magnetic supported uric acid-based compound (Fe3O4@SiO2@CPTMS@UA) was prepared, characterized and used as a capable adsorbent for removal of the Cd(II), Ni(II) and Pb(II) ions from aqueous solution. The Freundlich and Langmuir adsorption isotherms have been used to evaluate the adsorption behaviors. The high correlation coefficient of the Langmuir model (R+2 > 0.99) reveals that the Langmuir model offers the better coordination with the experimental results and so the model of adsorption of Cd2+, Ni2+, and Pb2+ on the adsorbent is more compatible with the Langmuir model, and the maximum adsorption capacity for the Cd, Ni, and Pb ions are about 285.7, 45.06 and 145.09 mg/g. Then, the corresponding Cd-complex (Fe3O4@SiO2@CPTMS@ UA@Cd) was also prepared, characterized and applied as an efficient heterogeneous nano-catalyst for the synthesis of diverse tetrazoles.

The anchoring of a Cu(ii)-salophen complex on magnetic mesoporous cellulose nanofibers: green synthesis and an investigation of its catalytic role in tetrazole reactions through a facile one-pot route

Today, most synthetic methods are aimed at carrying out reactions under more efficient conditions and the realization of the twelve principles of green chemistry. Due to the importance and widespread applications of tetrazoles in various industries, especially in the field of pharmaceutical chemistry, and the expansion of the use of nanocatalysts in the preparation of valuable chemical reaction products, we decided to use an (Fe3O4@NFC@NSalophCu)CO2H nanocatalyst in this project. In this study, the synthesis of the nanocatalyst (Fe3O4@NFC@NSalophCu)CO2H was explained in a step-by-step manner. Confirmation of the structure was obtained based on FT-IR, EDX, FE-SEM, TEM, XRD, VSM, DLS, TGA, H-NMR, and CHNO analyses. The catalyst was applied to the synthesis of 5-substituted-1H-tetrazole and 1-substituted-1H-tetrazole derivatives through multi-component reactions (MCRs), and the performance was assessed. With advances in science and technology and increasing environmental pollution, the use of reagents and methods that are less dangerous for the environment has received much attention. Therefore, following green chemistry principles, with the help of the (Fe3O4@NFC@NSalophCu)CO2H salen complex as a nanocatalyst that is recyclable, cheap, safe, and available, the use of water as a green solvent, and reduced reaction times, the synthesis of tetrazoles can be achieved.
