“…Large and broadly distributed Pd NPs prepared by the NaBH 4 reduction of a Pd precursor in the presence of P4VP cross-linked by 2% of divinyl benzene have been utilized for the synthesis of 5-substituted 1-H tetrazoles by one-pot reactions of aryl halides, K 4 [Fe(CN) 6 ], and sodium azide in the presence of potassium carbonate . The authors report comparatively high product yields for some substrates and easy recovery; however, the catalyst does not appear optimized.…”

Nanoparticle (NP)/polymer nanocomposites received considerable attention because of their important applications including catalysis. Metal and metal oxide NPs may impart catalytic properties to polymer nanocomposites, while polymers with a different structure, functionality, and architecture control the NP formation (size, shape, location, composition, etc.) and in this way, govern catalytic properties of nanocomposites. In this review we will discuss the influence of the polymer nanostructure (thin or grafted layers, polymer ordering, polymer nanopores), architecture (branched vs linear), functional groups (coordinating or ionic), specific properties (reducing, stimuli responsive, conductive), etc. on the formation of metal or metal oxide NPs and the catalytic behavior of the nanocomposites. The development of novel and efficient catalysts is crucial for progress in chemical sciences, and this explains a huge number of publications in this area in recent years. Taking into consideration previous review articles on NP/polymer catalysts, we limited this review to a discussion of a narrow temporal scope (2017–April 2019), while embracing a broad subject scope, i.e., considering any polymers and NPs which form catalytic nanocomposites. This gives us a unique view of the field of catalytic polymer nanocomposites and allows understanding of where the field is going.

Advances in Tetrazole Synthesis – An Overview

Most of the active pharmaceutical ingredients (API) contain the tetrazole ring, thus making them of vast significance in new drug design descriptors. With this importance in view, enormous studies are being carried out on the synthesis of tetrazole derivatives. The methods of its synthesis are [3+2] cycloaddition, multicomponent reactions, microwave‐assisted synthesis using heterogeneous and homogeneous catalysts. Hence, it is necessary to highlight the green catalysis that would be more environmentally benign and economically viable. In this review, we discuss the tetrazole synthesis processes carried out in the presence of heterogeneous and homogeneous catalysts. These catalytic materials gave higher product yield in a shorter reaction time and were reusable.

For the first time, metal‐exchange in a magnetic metal–organic framework (MOF) via tandem magnetization and post‐synthetic modification has been developed. The new magnetic mixed‐metal metal–organic framework nanocomposite, CoFe2O4/[Cu0.63/Zn0.37‐TMU‐17‐NH2] (CoFe2O4/[Cu/Zn‐MOF]) has been synthesized by immersing the CoFe2O4/Zn‐TMU‐17‐NH2 (CoFe2O4/Zn‐MOF) as a template in DMF solution of Cu (II) salts. CoFe2O4/[Cu/Zn‐MOF] showed to be a highly reactive and easily recoverable magnetic catalyst for the preparation of tetrazole derivatives via one‐pot three‐component reactions of different aldehydes with hydroxyl amine hydrochloride and sodium azide. Our results (Fourier transform‐infrared, inductively coupled plasma‐optical emission spectroscopy, powder X‐ray diffraction, field emission‐scanning electron microscopy, energy‐dispersive X‐ray spectroscopy‐mapping and vibrating‐sample magnetometer) show successful partial metal‐exchange in which the framework integrity remained intact during the metal‐exchange process.
