The crystalline product appears less stable than the diazide, spontaneously decomposing, sometimes explosively [1], It was rated as too unstable for use as a practical detonator or explosive [2], Lead(IV) acetate azide (probably the triacetate azide) is also rather unstable, evolving nitrogen above 0°C with precipitation of lead(II) azide [3], Lead(IV) azide will be considerably more endothermic than the lead(II) salt.

Lead (IV) Azide. Treatment of PbsCL with aq HN3 soln yielded a yel-red soln with a considerable Pb(IV) azide content. Normal HNS soln and Pb304 gave compds of PbN to PbNI0, while coned HN3 solns yielded a compd slightly lower than PbN12. These aq Pb(IV) azide solns decompd spontaneously with evolution of N2 and pptn of Pb(N3)2. Attempts to prepare solid Pb(IV) azide by...

Earlier work using lead(IV) azide or persulfate mediated by iion as oxidant has beat reviewed this last procedure, a radical redox one, can work very well (Scheme 47). Dimes can undergo 1,4-ad-ditimi with lead(IV) azide " reactions with steroid alkenes are varied (refs. 152,154 and references cited therein, and Section 3.5.11) but can yield the 1,2-adducts. 

Lead(IV) azide yields 1,4-diazides from l,3-dienes. Whilst q cloadditions are beyond the scope of this review, the sequence of Scheme 93 is potentially important 1,3-dienes undergo asymmetric IMels-Alder reactions with an a-diloronitroso derivative of qnandrosteione with hi ee, and die N—O... 

Steroidal alkenes, with lead(IV) azide/acetate, can yield cleaved derivatives such as (87),or its des-azido analog, or the uncleaved azido ketone,or the allylic azide, according to conditions, as well as the 1,2-diazi s mentioned earlier (Section 3.S.3.2). 

Although satisfactory methods for the preparation of lead(II) azide, Pb(Nj)2, are available in the literature, there is no authentic isolation of lead(IV) azide, Pb(Ns) . The isolation of lead(IV) chloride suggests the existence of lead(IV) azide, but the work of Moller and Lieber has thus far indicated only its qualitative existence without its successful isolation and characterization. Lieber and Keane were the first to attempt the synthesis of lead(IV) azides of the types RaPbNs, R Pb(N3)2, and RPb(Ns)a, in which R is a group that can stabilize the lead-nitrogen linkage and thus produce a stable derivative of the azide of tetravalent lead. This expectation was realized for the case in which R is a phenyl group.
