[(η5-C5Me4CH2R)Ru(η6-arene)]+ and [(η5-C5Me4CH2R)Ru(CH3CN)3]+ Compounds Possessing Pendant Arms
摘要:
[(eta(5)-C5Me4CH2)Ru(eta(6)-arene)](+) , [eta(5)-C5Me4CH2R)Ru(CH3CN)(3)](+) (R = OH, OR, and NR1R2), and related compounds possessing pendant arms are synthesized by the attack of water, alcohol, alkoxide, or amine nucleophiles on the methylenic carbon atoms of the readily available tetramethylfulvene complex [(eta(6)-C5Me4CH2)(RuCl)-Cl-11(mu-Cl)](2) (1) or its simple acetonitrile derivative, [(eta(6)-C5Me4CH2)Ru-11(CH3CN)Cl-2] (1a). The [(eta(5)-C5Me4CH2R)Ru (eta(6)-arene)](+) compounds can generally be quantitatively converted back into [(eta(5)-C5Me4CH2R)Ru(CH3CN)(3)](+) species by UV photolysis in CH3CN.

Facile syntheses of water-soluble [Cp*Ru(arene)]Clcompounds exploiting the extraordinary properties of [Cp*Ru(μ3-Cl)]4 in aqueous media are described. These methods produce no byproducts, involve little to no workup, and are applicable to almost any simple arene.
