Synthetic and structural studies of l-sila-2,5-diaryltetrazenes

Article abstract of DOI:10.1002/cber.19971301105

The reaction between aryl azides and lithiated aryl amines leads to tetrazenes 3 and 9 which contain a chain of four nitrogen atoms. Reaction with different halosilanes gives the cyclic silatetrazenes 10, 12, and 15 where substitutents on the silicon vary from alkyl to hydrogen and chlorine atoms. The structures of 10,12, and 15 in the solid state are reported. Variation of the solvent and the Lewis acidity of the halosilane influence the ratio of silatetrazene to side products, bissilylated amines. These effects are studied for different halosilanes.
