摘要：

Reduction of [Ru(acac)(3)] with zinc in THF/H2O Provides a range of coordination and organometallic complexes containing Ru-II(acac)(2), whose chemistry is reviewed. Most of these compounds, including those containing alkenes, undergo reversible one-electron oxidation to their Ru-III(acac)(2) counterparts, and the alkene-ruthenium(III) cations have been detected by spectroclectro-chemistry. The cations derived from the chelate N-donor ligands o-CH2=CHC6H4NMe2 and o-PhC-=CC6H4NMe2 have been isolated and structurally characterized. Comparison of the metrical data establishes that, whereas the alkene is less firmly bound to Ru-III than to Ru-II, the alkyne is bound about as strongly to Ru-III as to Ru-II. Some uncharged nucleophiles (pyridine, diethylamine, PPh3) react with the cationic Ru-III complexes to give unusual, paramagnetic Ru-III-C sigma-bonded chelate complexes. (C) 2004 Elsevier B.V.
