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.

Reactions of organotin tetrazoles: synthesis of functionalised poly-tetrazoles

Journal of the Chemical Society, Perkin Transactions 1, 1999
Reaction of 1,2-bis[2-(tributylstannyl)tetrazol-5-yl]benzene with 1,2-dibromoethane (1∶10) yields the 1-N,1-N′-ethylene bridged cyclophane (1) while similar reactions with larger excesses (1∶25) of 1,n-dibromoalkanes yield 1,2-bis[2-(bromoalkyl)tetrazol-5-yl]benzenes along with the unsymmetrical 1-N,2-N-substituted tetrazole isomers.

Theoretical study of synthetic reaction of tetrazole and tetrazolate anion

International Journal of Quantum Chemistry, 2000
Tetrazole (H2CN4) and tetrazolate anion (HCN) are high-energy compounds with a five-membered ring-type structures, which can be easily synthesized by HCN and HN3 and by HCN and N, respectively, in an irreversible reaction. The ab initio methods including MP2/6-31G**, B3LYP/6-31G**, B3LYP/6-311+G(2d,p), and CBS/QB3 from Gaussian 98 program are employed ...
