Abstract

The complexes Ru(CO)₂L₂(AL-2H) (AL = alizarin; L = PPh₃, PCyc₃, PBu₃, P(m-NaSO₃C₆H₄)₃), Ru(CO)(dppe)-(PBu₃)(AL-2H), and RuH(CO)L₂(AL-H) (L = PPh₃, PCyc₃), and Ru(CO)₂L₂(AR-2H) (AR = anthrarobin; L = PBu₃) were prepared by reactions of Ru₃(CO)₁₂, L, and AL, and the complexes RuH(CO)(PPh₃)₂(AL-H), RuH-(CO)(PPh₃)₂(QN-H) (QN = quinizarin), and RuH(CO)(PPh₃)₂(LQN-H) (LQN = leucoquinizarin) are prepared by reactions of RuH₂(CO)(PPh₃)₃ with AL or QN. The AL-2H and AR-2H ligands act as 1,2-catecholates, whereas the AL-H, QN-H, LQN-H ligands are 1,9-o-acylphenolate ligands. RuH(CO)(PPh₃)₂(AL-H) is characterized by X-ray crystallography. The electrochemistry of these complexes is examined, and the semiquinone complexes [Ru(CO)₂L₂(AL-2H)]⁺ (L = PPh₃, PCyc₃, PBu₃) and [Ru(CO)(dppe)(PBu₃)(AL-2H)]⁺ are generated by chemical oxidation and were characterized by EPR and IR spectroscopy. The photophysical properties are also reported.
