Abstract

The four intramolecularly coordinated azidoalanes R₂Al(N₃) and RAltBu(N₃) (R = (CH₂)3-NMe₂ (1b, 3b), 2-(Me₂NCH₂)C₆H₄ (2b, 4b)) were synthesized by reaction of the corresponding aluminum chlorides (1a-4a) with an excess of dry sodium azide in refluxing toluene or toluene/THF. The structures of the products were deduced from ¹H, ¹³C, and ²⁷Al NMR spectra and were confirmed by X-ray structural determinations of 1a, 1b, and 2b. The compounds of type 1 and 2 contain pentacoordinated Al atoms, whereas the alanes ot type 3 and 4 show tetracoordination of the central Al atoms.
