“…There is a single report about the fabrication of tetrazole derivatives employing a solid catalyst preparation. [44] The latter was fabricated by preparing a magnetic Fe 3 O 4 core covered with a silica layer grafted with 3-(chloropropyl)trimethoxysilane. Anchoring a Phen (1,10-phenanthroline) moiety was achieved upon reflux and, finally, treatment with Pd(OAc) 2 delivered the catalyst material with a 3.6 wt% loading.…”

This review aims to collect and analyze recent results with respect to the use of varied palladium preparations in the synthesis of five-membered nitrogen heterocycles including condensed derivatives. Results have been selected with focus on studies of the last three years. Furthermore, a common feature of all methods treated here is that the nitrogencontaining five-membered ring is formed via ring closing of appropriate starting materials. Selected examples discussed will reveal that a plethora of products from small monocycles to condensed multi-ring systems can be successfully accessed. Major features are wide product ranges, high product yields and stereoselectivities often achieved under mild reaction conditions.

Noble metal nanoparticles supported on porous silica materials represent an important class of heterogeneous catalysts. Various synthesis strategies have been developed, including the application of ligand‐assisted metal precursors, multistep synthesis procedures, post‐synthetic modifications, and magnetic mesoporous silica particles. Emphasis has been laid on the introduction of green procedures, based on the utilization of environmentally friendly solvents, efficient stabilizing agents, non‐toxic reagents, and mild reaction conditions. Palladium nanoparticles have long been recognized as the most efficient catalysts in a wide range of organic transformations, including the Heck, Suzuki, Stille, and Sonogashira reactions. Although these transformations have been extensively investigated in homogeneous catalytic systems, the application of heterogeneous catalysts, including silica‐supported Pd0 nanoparticles, has gained in increasing importance. The aim of this review is to provide an outlook on the current research progress achieved on the development of novel synthetic procedures, affording highly dispersed Pd0 nanoparticles immobilized on porous silica materials, which proved to be efficient and recyclable catalysts in C–C coupling and cross‐coupling reactions.

“…Tetrazoles have a lot of positive attributes, like low basicity, high acidity, a many of nitrogen atoms, high stability, as well as a high formation enthalpy. They are used as analytical reagents in science, as lipophilic spacers in drug design, as useful antitumor and anticancer agents, peptide inhibitors, beginning materials for making propellants, energetic materials, and N-containing compounds [7][8][9][10][11][12][13]. Since the tetrazole ring is the heterocyclic analogue of compounds like cis-amide and carboxylic acid, it is used to create novel medications.…”
