The properties of chlorine azide resemble those of bromine azide. Pon-sold has taken advantage of the stronger carbon-chlorine bond, i.e., the resistance to elimination, in the chloro azide adducts and thus synthesized several steroidal aziridines. 5a-Chloro-6 -azidocholestan-3 -ol (101) can be converted into 5, 6 -iminocholestan-3l -ol (102) in almost quantitative yield with lithium aluminum hydride. It is noteworthy that this aziridine cannot be synthesized by the more general mesyloxyazide route. Addition of chlorine azide to testosterone followed by acetylation gives both a cis- and a trans-2iddMct from which 4/S-chloro-17/S-hydroxy-5a-azidoandrostan-3-one acetate (104) is obtained by fractional crystallization. In this case, sodium borohydride is used for the stereoselective reduction of the 3-ketone... 

Although chlorine azide and bromine azide tend to give some dihalogen adducts, these reagents have been used in the presence of alcohol, ester and epoxy functions without interference.In the case of 17a-acetoxy-A -progesterone, a selective addition to the 6,7-double bond is obtained. ...

The ground state structure is not known but probably is planar in analogy with hydrazoic acid and chlorine azide. D0(N2—NCN) = 0.3 0.1 cV, CN) = 4.0 + 0.2 eV. The absorption spectra of N2CN in cyclohexane in the near ultraviolet have been observed in two regions with maxima at 2750 and 2200 A, the latter about 20 times as strong as the former [Marsh and Hermes (662)].
