摘要：

[Cp*RuOMe](2) (1) reacts with phenols by successive exchange of one and two OMe groups for the phenolate group, forming mixed mu-methoxy-mu-phenolato complexes (5) and bis(mu-phenolato) dimeric complexes (6) successively. The latter, by can intramolecular rearrangement, convert into Cp*Ru(eta(5)-oxocyclohexadienyl) complexes (7). With phenol and 2-methyl-5-isopropyl-phenol (carvacrol) the stepwise reactions were followed by NMR spectroscopy. Using 2,4-di-tert-butylphenol, both the mono(phenolato) (5c) and bis(phenolato) (6c) complexes have been isolated. The latter complex is obtained best from Cp*Ru(proline) (8) and 1. Complex 5c was characterized by an X-ray structure. The molecular geometry is very similar to the one found for 1.
