Treatment of [Ru]-CCPh (1, [Ru] = (η5-C5H5)(dppe)Ru, dppe = Ph2PCH2CH2PPh2) with trimethylsilyl azide afforded the cationic nitrile complex {[Ru]NCCH2Ph}[N3
Efficient uncatalyzed conversion of primary and secondary thioamides into 1-substituted, 5-substituted, 1, 5-disubstituted and annulated tetrazoles
El-Ahl, Abdel-Aziz S.,Amer, Fatty A.,Elbeheery, Akram H.
experimental part, p. 2226 - 2235 (2012/03/26)
Unprecedented high-yield simple and mild conversion of primary aliphatic and aromatic thioamides into 5-substituted tetrazoles on treatment with a combination of tetrachlorosilane and sodium azide in refluxing acetonitrile has been achieved. Secondary acyclic, cyclic, and heterocyclic thioamides could also be transformed in high yields into 1-substituted, 1,5-disubstituted, or annulated tetrazoles under the same reaction condition.

Improved Schmidt synthesis of 1,5-disubstituted 1H-tetrazoles from ketones
Suzuki,Hwang,Nakaya,Matano
, p. 1218 - 1220 (2007/10/02)
On treatment with an excess of sodium azide in the presence of titanium(IV) chloride in boiling acetonitrile, both aliphatic and aromatic ketones are smoothly converted to 1,5-disubstituted 1H-tetrazoles in high yields.
