The reaction of sodium azide with chlorosilanes in hexamethylphosphoric triamide or dimethylformamide at room temperature affords a high yield preparation of silyl azides, e.g. Me₃SiN₃,Me₂Si(N₃)₂, PhMeSi(N₃)₂ and Ph₂Si(N₃)₂. For characterization, the azides may be converted to silyphosphiimies, R₃Si-N=PPh₃.
