摘要：

Three novel pyridine functionalized N-heterocyclic silanes, bearing chloride and azide moieties, were synthesized and characterized by NMR spectroscopy (H-1, C-13, Si-29), mass spectrometry, elemental analysis, and single-crystal XRD. The molecular structures show a comparably strong dative interaction of the pyridine-N with the Si center, formally inducing a penta-coordination arrangement at the silicon(IV). Under appropriate conditions, the silylazides, presented in this work, might be able to thermo- or photolytically liberate gaseous nitrogen giving rise to a promising synthetic option to access a variety of new transition metal silylene complexes with potential applications in various catalytic reactions.
