Copper-decorated core–shell structured ordered mesoporous containing cobalt ferrite nanoparticles as high-performance heterogeneous catalyst toward synthesis of tetrazole

Scientific Reports, 2023
The present work describes the synthesis of copper immobilization on CoFe2O4/MCM-41 as a catalyst, which is created by attaching copper and ligand (N-phenyl anthranilic acid (PA)) on the surface of CoFe2O4/MCM-41 (CoFe2O4/MCM-41/PA/Cu).

An Ugi Reaction/Intramolecular Cyclization/Oxidation Cascade towards Tetrazole-Linked Dibenzoxazepines [PDF]

, 2021
A series of tetrazole-linked dibenzo[ b, f ][1,4]oxazepines is synthesized through a short sequence involving an Ugi tetrazole reaction. The intermediate tetrazole undergoes a potassium carbonate mediated S NAr cyclization, followed by oxidation to ...

2-Methyl-3-{4-[2-(1H-tetrazol-5-yl)ethylamino]phenyl}-3H-quinazolin-4-one

Molbank, 2010
This present work aims at synthesizing a novel tetrazole from quinazolinone. 3-(4-Aminophenyl)-2-methyl-3H-quinazolin-4-one is converted into a nitrile by reacting it with acrylonitrile and triton B.
