A unique and novel reaction between benzyl azides and aryl azides is described to synthesize aryl nitriles and anilines concurrently, which is catalyzed with a photoactivated diruthenium complex. N-Unsubstituted imines (N-H imines) are generated first from benzyl azides, followed by the hydrogen transfer reaction between N-H imines and aryl azides. A wide range of aryl nitriles and anilines were synthesized under neutral and mild reaction conditions.

Reaction of N-phenyl-2,5-dimethyl-3,4-diphenylcyclopenta-2,4-dienimine (6) with Ru3CO12 formed two isomers of {[2,5-Me2-3,4-Ph2(η5-C4CNHPh)]Ru (CO)(μ-CO)}2 (8-trans and 8-cis). Photolysis of 8 under a H2 atmosphere led to the formation of the aminocyclopentadienyl ruthenium hydride [2,5-Me2-3,4-Ph2(η5-C4CNHPh)]Ru( CO)2H (9-H). 9-H reduced benzaldehyde slowly at 75 °C to give benzyl alcohol and 8. Protonation of 9-H with triflic acid produced {[2,5-Me2-3,4-Ph2(η5-C4CNH2 Ph)]Ru(CO)2H}OTf (11-H), which reacted rapidly with benzaldehyde at -80 °C to give benzyl alcohol and [2,5-Me2-3,4-Ph2(η5-C4CNHPh)]Ru( CO)2OTf (9-OTf). Reaction of 9-OTf with H2 and base led to the re-formation of 9-H. These reactions provide the transformations required for a catalytic cycle for hydrogenation of aldehydes.
