摘要：

Reaction of the dichloride dimer [{Ru(eta3:eta3-C10H16)Cl(mu-Cl)}2] (3) with beta-diketones or their sodium salts results in the formation of the neutral chelate complexes [Ru(eta3:eta3-C10H16)Cl(R.CO.CH.CO.R')] (R=R'=CH3 (7); R=CH3, R'=CF3 (8)). The equatorial (most abundant) isomer of 8 (8a) has been characterised by X-ray crystallography. Attempts to remove the chloride ligand in compounds such as 7 (via Ag+) to form cationic aqua species were unsuccessful. However, analogous reactions with the cationic chelate complexes [Ru(eta3:eta3-C10H16)Cl(L-L)][BF4] (L-L=2,2'-bipyridyl (4); 1,10-phenanthroline (5)) resulted in the isolation of the aqua compounds [Ru(eta3:eta3-C10H16)(L-L)(OH2)][BF4]2 (10 and 11) in good yields. Attempts to generate oxo species derived from 10 and 11 by both electrochemical and chemical means were unsuccessful.
