Reaction of bis(aryldiazenido) complexes of rhenium with bromine: Preparation of new diazo derivatives

The reaction of bis(aryldiazenido) [Re(ArN2)2P3]BPh4 complexes with Br2 is presented. The synthesis of aryldiazene-aryldiazenido ReBr2(ArN2)(ArNNH)P2 derivatives was achieved by reacting bis(aryldiazenido) with hydride-donor species. Protonation studies on aryldiazene complexes are also reported.
