摘要：
Treatment of [Ru(PPh3)(3)Cl-2] with the Schiff base ligand H(2)salen in THF at reflux afforded a neutral Ru-III-salen complex [Ru-III(salen)(PPh3)Cl] (1). Interaction of [RuHCI(CO)(PPh3)(3)] with Ru-II-salen under similar conditions gave a neutral Ru-II-salen complex [Ru-II(salen-NH)(PPh3)(CO)] (2). In its formation one of the imine bonds was nucleophilically attacked by hydride to give a mixed imine-amine ligand. The two complexes have been spectroscopically characterized, and the crystal structures of 1 center dot 2CH(2)Cl(2) and 2 center dot CH2Cl2 have been established by X-ray crystallography.
