Azobenzene is a weak base, but undergoes protonation at one nitrogen with a pKa = -2.95. It functions as a Lewis base, e.g. toward boron trihalides. It binds to low valence metal centers, e.g. Ni(Ph2N2)(PPh3)2 is well characterized. It oxidizes to give azoxybenzene. Hydrogenation gives diphenylhydrazine.
