Chemical compound

Iron(III) azide, also called ferric azide, is a chemical compound with the formula Fe(N3)3. It is an extremely explosive, impact-sensitive, hygroscopic dark brown solid. This compound is used to prepare various azidoalkanes, such as n-butyl azide, from alkenes via formation of alkylboranes and subsequent anti-Markovnikov addition of azide group.[2]

## Preparation

[edit]

This compound is prepared by the reaction of sodium azide and iron(III) sulfate in methanol:[2]

6 NaN3 \+ Fe2(SO4)3 → 2 Fe(N3)3 \+ 3 Na2SO4

Iron(III) azide can also be formed by pulse gamma-irradiation of a mixture of iron(II) perchlorate, sodium azide, and hydrogen peroxide.[3] Under these conditions, a neutral N3 radical is formed, which oxidizes the iron(II) to iron(III); the iron(III) then promptly combines with azide ions.
