Abstract:
[Ru(II)(L)(CO)L1] (L = octaethylporphyrin, L1 = EtOH, py), generated from [Ru(II)L(CO)L1] electrochemically or by Br2 oxidation, react with ≥ 2 equivalents of L2 (L2 = PBu3, PPh3) to give [Ru(III)L2L2] (I). I were also prepared electrochemically (and reversibly) from [Ru(II)L2L2]. The cyclic voltammogram of I (L2 = PBu3) shows a wave attributable to the cation radical [Ru(III)(L)L2]2+ (II). II (L2 = PBu3) was characterized by ESR and UV/visible spectroscopy.
