Biosynthesis and characterization of magnetic starch-silver nanocomposite: catalytic activity in eco-friendly media

AgNPs@Fe3O4-nanostarch nanocomposite was prepared using Helicteres isora L. extract as a reducing and stabilizing agent. FESEM, EDS, TEM, FT-IR, XRD, VSM, and elemental mapping were utilized to characterize the synthesized nanocomposite. The nanocomposite was applied as a magnetically separable and reusable catalyst for the efficient preparation of various arylaminotetrazoles by reacting different arylcyanamides with sodium azide in high yields without forming hydrazoic acid. We report the oxidation of benzyl alcohol to benzaldehyde by hydrogen peroxide under solvent-free conditions in good yields using AgNPs@Fe3O4-nanostarch as a magnetically separable and reusable catalyst. The catalyst showed high catalytic performance in the reduction of 4-NP, CR, RhB and MB using NaBH4 as the source of hydrogen in an aqueous medium. The products were formed in good yields through a simple method and facile work-up. In addition, the catalyst could easily be separated from the reaction mixture using an external magnet and reused for at least 5 runs with no significant loss of catalytic activity.

Iron-promoted sulfur sequestration for the substituent-dependent regioselective synthesis of tetrazoles and guanidines

We have established a facile and versatile synthetic methodology for the construction of tetrazoles and guanidines in the presence of an eco-friendly, inexpensive, easily available iron reagent. Aromatic thioureas with electron-donating substituents produced their respective target products in quantitative yield. In contrast, when electron-withdrawing substituted aromatic thioureas were used, the expected products were obtained in reduced yield. However, the desired products were obtained in good yield at moderate temperature. In addition, mechanistic studies revealed that the synthetic route involved iron-based subsequent reactions of addition and removal of sulfur.

Cobalt-promoted one-pot reaction of isothiocyanates toward the synthesis of aryl/alkylcyanamides and substituted tetrazoles

[Figure not available: see fulltext.] The synthesis of cyanamides and tetrazoles from isothiocyanates through tandem reaction using cobalt catalyst has been demonstrated. In the case of tetrazole preparation, the reaction involved addition/desulfurization/nucleophilic addition/electrocyclization, whereas aromatic cyanamides were constructed from isothiocyanates through addition/desulfurization. Cheap cobalt sulfate was used for the synthesis of various cyanamides and tetrazoles. In addition, cobalt catalyst was found to be desulfurization reagent that has not been previously reported. The final products have been obtained from starting precursors in good to high yield.
