摘要：The present work involves an attempt to prepare two Ruthenium(II) complexes [Ru(bp y)3]2+ (I) and [Ru(phen)3]2+ (II) by simple and effective one-pot synthesis in a greener way and we have succeeded in achieving the target compounds in very good yields. Furthermore, we have studied extensively the photochemical reduction of complex I and II , *[Ru(NN)3]2+ in their excited states with various aromatic amines in the absence and presence of oxygen molecules by the luminescence quenching technique. The quenching rate constants, kq for each photoredox reactions have been determined using Stern - Volmer analysis. The results exhibit an interesting trend which depends on the nature of the quencher. In particular, the result proves the efficient interacting mechanism of oxygen with the excited state of *[Ru(NN) 3 ] 2+ .
