Hydride complexes were prepared.Their reactions with arenediazonium cations led to the synthesis of 2 and BPh4 (R = Ph, 4-MeC6H4,, or 4-MeOC6H4) complexes which were characterized by 1H and 31P n.m.r. data (with 15N isotropic substitution).The compounds 2 were also prepared.The reaction of the bis(aryldiazene) derivatives with NEt3 led to a new five-co-ordinate aryldiazenido complexes BPh4 (R = Ph or 4-MeC6H4).Protonation of the diazenido compounds with CF3CO2H and HBF4 gave the six-co-ordinate mono(diazene) BPh4 and the five-co-ordinate BPh4 (R = 4-MeC6H4) derivatives, respectively.Infrared and 1H and 31P n.m.r. data for these complexes are reported.
