Tetrazoles: XLVII. A route to tetrazole-containing dendrimers

Russian Journal of Organic Chemistry, 2004
The reaction of 5-methylsulfonyl-1-phenyltetrazole with pentaerythritol in acetonitrile in the presence of sodium hydroxide gave tetrakis(1-phenyltetrazol-5-yloxymethyl)methane. Sulfur-containing analog of the latter was obtained by alkylation of 1-phenyl-4,5-dihydrotetrazole-5-thione with 1,3-dibromo-2,2-bis-(bromomethyl)propane.

Synthesis of (difluoroamino)tetrazoles and [(difluoroamino)alkyl]tetrazoles

Russian Chemical Bulletin, 2000
(Difluoroamino)tetrazoles were obtained by direct fluorination of 5-aminotetrazoles with gaseous fluorine. Reactions of 2-(oxoalkyl)- and 2-(hydroxyalkyl)tetrazoles with difluoroamine yielded [(difluoroamino)alkyl]tetrazoles.

Relation between the substituent effect and aromaticity in tetrazoles, protonated tetrazoles and tetrazolate derivatives

Journal of Molecular Structure: THEOCHEM, 2007
Abstract The energies, geometries and aromaticity of a series of 5R tetrazoles [R = NH 2 , OH, OCH 3 , SCH 3 , H, CH 3 , F, Cl, BH 2 , CF 3 , CN, NO, NO 2 ], their anions and protonated forms in the gas phase have been calculated with the DFT/B3LYP method at the 6-31++G ∗∗ level.
