Phys. 50, 1453 (1972); Almenningen et al., Acta Chem. Scand. 27, 1531 (1973).
Properties: Clear, colorless, oily liquid. Caution: The pure azide detonates violently upon thermal, electrical or mechanical shock! Can be handled relatively safely in solvents. Half-life of a 27% soln in acetonitrile is 15 days at room temp, more stable at lower temps.
Use: In organic synthesis. Has a versatility and scope of chemical reactivity that is very broad and useful, e.g. reacts with alkanes to give primary alkylcyanamides: Anastassiou et al., J. Am. Chem. Soc. 87, 2296 (1965).
