“…[42][43][44][45][46][47][48][49] Likewise, tetrazole derivatives have various biological properties which are generally formed from [3 + 2] cycloaddition of azide and benzonitrile derivatives in the presence of practical catalysts. [50][51][52][53][54] Recently, 5-substituted tetrazoles are used as an isosteric replacement for carboxyl groups. [55] Tetrazole derivatives have various applications in coordination chemistry, organic chemistry, agriculture, the photographic industry, explosives, and medicinal chemistry.…”

This work discusses the synthesis and characterization of new copper Schiff‐base complex of 3,4‐diaminobenzophenone stabilized on magnetic MCM‐41 as a magnetically reusable catalyst. At first, Fe3O4 magnetic nanoparticles were synthesized via a chemical co‐precipitation method using FeCl2.6H2O and FeCl3.6H2O in basic solution of ammonia. Then magnetic MCM‐41 were synthesized via Fe3O4‐doped into mesoporous channels of MCM‐41. Further a new copper Schiff‐base complex of 3,4‐diaminobenzophenone was supported on magnetic MCM‐41 and was used as a practical and magnetically reusable catalyst in organic reactions such as homoselective synthesis of tetrazole and pyranopyrazole derivatives. This catalyst was characterized by several techniques such as scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDS), wavelength dispersive X‐ray spectroscopy (WDX), thermogravimetric analysis (TGA), X‐ray powder diffraction (XRD), atomic absorption spectroscopy (AAS), Fourier transform‐infrared spectroscopy (FT‐IR), Brunauer–Emmett–Teller (BET), and vibrating sample magnetomter (VSM). This catalyst display good selectivity, high activity, stability and facile magnetic separation. Therefore, this catalyst can be recycled for several times without significant loss of its catalytic efficiency.

“…There is a growing interest for tetrazoles, 1 namely 2,5-disubstituted tetrazoles (2,5-Tz) (Fig. 1) that can be used as ester 2 and amide bioisosteres, 3 deconvolution agents for the identification of therapeutic targets, 4 or directing groups in transition metal-catalyzed C–H insertion.…”

Herein, a straightforward method for the construction of tetrazole derivatives has been achieved through Pd-catalyzed isocyanide insertion reactions, which is a good extension for the response of multi-molecule isocyanides. The Ugi-N 3 reaction was introduced to the transformation to enrich the diversity of skeleton structures. The commercially available starting materials and moderate to good yields make this method a valuable tool for generating N-containing heterocyclic compounds.
