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
络合物Ru(CO)2L2(AL-2H)(AL =茜素; L = PPh3,PCyc3,PBu3,P(m-NaSO3C6H4)3),Ru(CO)(dppe)(PBu3)(AL-2H),通过Ru3(CO)12反应制得RuH(CO)L2(AL-H)(L = PPh3,PCyc3)和Ru(CO)2L2(AR-2H)(AR =蒽环素; L = PBu3), L和AL,以及配合物RuH(CO)(PPh3)2(AL-H),RuH(CO)(PPh3)2(QN-H)(QN =奎尼萨林)和RuH(CO)(PPh3)2 (LQN-H)(LQN = leucoquinizarin)通过RuH2(CO)(PPh3)3与AL或QN反应制备。AL-2H和AR-2H配体充当1,2-儿茶酚酸酯,而AL-H,QN-H,LQN-H配体则是1,9-邻酰基苯酚酸酯配体。RuH(CO)(PPh3)2(AL-H)用X射线晶体学表征。检
