An ESR study on structures of a series of silylnitrenes

Structures of a series of silylnitrenes formed from silyl azides were investigated by means of ESR. γ-Irradiation and photo-illumination of all the silyl azides resulted in the formation of triplet states even for those having two or three Si-N3 groups in a molecule. ESR spectra of the silylnitrenes exhibited a part of the fine structure at around 820 mT. All the silyl azides studied gave nearly identical D-values (ca. 1.5cm-1) and much larger than those in phenylnitrenes. The results suggested that electron spins are localized in the nitrogen p-orbitals to a large extent and was interpreted in terms of a mono-silane linkage of nitrene, -Si-N:, i.e., interrupting spin delocalization.

Facile preparation of silyl azides with dipolar aprotic solvents

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.
