Reaction of 1,2-diphenylhydrazine with the gold oxo complex [(PPh3Au)3(μ-O)]BF4 gives a mixture of [(Ph3PAu)3(μ-N-1,4-C6H4-NHPh)]BF4 (1; 82%) and [(Ph3PAu)3(μ-N-1,2-C6H4-NHPh)]BF4 (2; 18%) in CH2Cl2 at ambient temperature. A crossover experiment using a 1:1 mixture of 1,2-diphenylhydrazine and 1,2-diphenylhydrazine-d10 indicates that the rearrangement process is intramolecular.
