Abstract

The nitriles 7e-k and 10 are methylated by methyl triflate to afford the N-methylnitrilium triflates 8e-k and 11 which are allowed to react with methyl azide to produce the tetrazolium triflates 9. F3CS03 and 12. F3CS03. The crystalline hexafluorophosphates 9. PF, and 12. PF, are obtained after anion exchange with ammonium hexafluorophosphate. Deprotonation of the tetrazolium cations 9c-g, j, k and 16 fur-nishes the corresponding ...
