Abstract

Fluoroiodomethane was allowed to react with the sodium salts of 5H-tetrazole and 5-aminotetrazole to give in each case the two corresponding isomers 1-fluoromethyl-5H-tetrazole (1a) and 2-fluoromethyl-5H-tetrazole (1b), as well as 1-fluoromethyl-5-aminotetrazole (2a) and 2-fluoromethyl-5-aminotetrazole (2b). The new tetrazoles were isolated and characterized by spectroscopic methods (IR, Raman, multinuclear NMR), mass spectrometry, and in the case of fluoromethyl-5-aminotetrazole the crystal structures of both isomers were obtained and discussed. Differential thermal analysis (DTA) gave insight in how a FCH2 moiety attached to a tetrazole effects the thermal behavior compared to its CH3 analog. In addition, the detonation parameters were calculated and compared to those of the corresponding methyltetrazoles. In addition, the preparation of energetic copper complexes of the new ligands was attempted. Complexes of copper(II) perchlorate and chlorate are crystallographically described and their energetic properties discussed.
