Benzenediazonium tribromide

Griess (1866 b) found that benzenediazonium tribromide (QHsN Br ) in the presence of ammonia is converted into phenyl azide in high yield. The reaction probably proceeds through phenyltriazene, as an intermediate which is subsequently oxidized to the azide by the tribromide ion (Scheme 6-14). [Pg.121]

The reaction of azide ions with diazonium ions is preferable to the classical synthesis of aryl azides which was found by Griess (1864d, 1866b) in the reaction of benzenediazonium tribromide with ammonia (see discussion in Sec. 6.4). [Pg.240]

Benzenediazonium Tribromide (Diazobenzene Tribromide), CsHs.N2.Br3 mw 264.95, N 10.58% orn-red ndls, mp 63-5°(dec), expl weakly on heating diffc sol in cold ale insol in w or erh. Can be prepd by treating a benzenediazonium chloride soln with an aq K bromide soln and by reacting bromine in a hydrobromic acid soln with a soln of benzenediazonium nitrate or sulfate. The dry comp is stable but in a humid atm it dec into 2,-4,6-tribromophenol. It rapidly dec in the presence of ale... [Pg.58]
