摘要
The complex [Ru(C5H5)Cl(PPh(3))(2)] reacted with 1 equivalent of dippe [dippe = 1,2-bis(diisopropylphosphino)ethane] in refluxing toluene to yield [Ru(C5H5)Cl(dippe)] 1. The complex [Ru(C(5)Me(5))Cl(dippe)] 2 was obtained by reaction of [(Ru(C(5)Me(5))(mu(3)-Cl))(4)] with a stoichiometric amount of dippe in CH2Cl2. The crystal structure of 2 has been determined. Both 1 and 2 are non-electrolytes in non-polar solvents. In alcohols, compound 2 has a strong tendency to dissociate chloride. In the presence of air, this compound binds O-2 irreversibly, yielding the dioxygen complex [Ru(C(5)Me(5))(O-2)(dippe)](+), which is isolable as the [BPh(4)](-) salt (3). The crystal structure of this-compound has also been determined. Both 1 and 2 reacted with SnCl2 in CH2Cl2 to yield the insertion derivatives [Ru(C(5)R(5))(SnCl3)(dippe)] (R = H 4 or Me 5). All compounds were characterized by NMR spectroscopy and microanalysis.
