Abstract
1-Dimethysilyltetrazole (1) has been prepared from 1H-tetrazole and chlorodimethylsilane in the presence of 2,6-lutidine, bis(1-tetrazolyl)dimethylsilane (2) from the reaction of 1H-tetrazole, dimethyldichlorosilane and triethylamine and 5-(trimethylsilylamino)-1H-tetrazole (3) from 5-amino-tetrazole monohydrate and hexamethyldisilazane. The reactions of 4-amino-1H-1,2,4-triazole with different amounts of hexamethyldisilazane gave rearrangement reactions yielding 1-trimethylsilyl-3-(trimethylsilyl)amino-1.2,4-triazole (4) and 1-trimethylsilyl-3-bis(trimethylsilyl)amino-1,2,4-triazole (5). The compounds were characterised by NMR spectroscopy (H-1, C-13{H-1} and Si-29 NMR), by 1R spectroscopy, mass spectrometry, elemental analyses and in the case of 3, 4 and 5 by determination of their crystal structures by X-ray diffraction. The structure of a cocrystallisate of 4-amino-1H-1,2,4-triazole with acetonitrile was also determined. Common structural distortions of silylated ring nitrogen atoms are discussed as well as hydrogen bonding motif's in the crystal structures.
