Aureggi, Valentina; Sedelmeier, Gottfried published the article 《1,3-Dipolar cycloaddition: click chemistry for the synthesis of 5-substituted tetrazoles from organoaluminum azides and nitriles》. Keywords: substituted tetrazole preparation; organoaluminum azide preparation nitrile dipolar cycloaddition.They researched the compound: 5-(4-Pyridyl)-1H-tetrazole( cas:14389-12-9 ).Electric Literature of C6H5N5. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:14389-12-9) here.
Conventional methods to prepare tetrazoles employ dangerous, toxic reagents. A route to these heterocycles using inexpensive and nontoxic dialkyl aluminum azides was developed. The cycloaddition occurred under mild conditions and tolerates a variety of functional groups. The low cost and ecocompatibility made this process attractive for large-scale preparation
