摘要：
The ruthenium(II) complexes [Ru(CF3CO2)(2)(CF(3)triphos)], [Ru-2(mu-Cl)(3)(CF(3)triphos)(2)]Cl, [RuH(CH3CN)(2)(CF(3)triphos)](CF3SO3) and [Ru(CH3CN)(3)(CF(3)triphos)](CF3SO3)(2) (CF(3)triphos = CH3C{CH2P(m-CF3C6H4)(2)}(3)) were prepared and characterized. The iridium complexes [Ir(COD)(CF(3)triphos)](+), [IrCl(CO)(CF(3)triphos)], [Ir(CO)(2)(CF(3)triphos)](+), [IrCl3(CF(3)triphos)] and [IrCl3-n(MeCN)(n)(CF(3)triphos)](CF3SO3)(n) (n = 1, 2 and 3) were also prepared and characterized. The coordination chemistries of these two elements with CF(3)triphos and with the unsubstituted ligand CH3C{CH2P(C6H5)(2)}(3) (Htriphos) are compared. It is shown that, relative to Htriphos, CF(3)triphos (a) stabilizes the iridium(I) relative to the iridium(III) oxidation state and (b) its cationic complexes are stronger Lewis acids.
