Reactions of organotin tetrazoles: synthesis of functionalised poly-tetrazoles
Journal of the Chemical Society, Perkin Transactions 1, 1999Reaction 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.

Bioisosterism involving replacement of a carboxylic acid substituent by 1H-tetrazole, yielding deprotonated carboxylate and tetrazolate under physiological conditions, is a well-known synthetic strategy in medicinal chemistry. To improve our overall understanding of bioisosterism, we have used this example to study the geometrical and energetic aspects

Theoretical study of synthetic reaction of tetrazole and tetrazolate anion
International Journal of Quantum Chemistry, 2000Tetrazole (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 ...
