or dppe afford [Ru(CO)LPH(OMe)Cy}], [Ru(CO)(CNCHMe-2,4,6)LPH(OMe)Cy}] or [Ru(CO)(dppe)PH(OMe)Cy}], resectively, in each case demonstrating a preference for dissociation of PPh rather than PH(OMe)Cy. Aerial oxidation of [Ru(CO)LPH(OMe)Cy}] results in oxidation of one carbonyl ligand with formation of the carbonato complex [Ru(OCO)(CO)LPH(OMe)Cy}]. The reaction of [Ru(CO)LPH(OMe)Cy}] with ethynyl
[RuHCl(CO)L] (L = PPh) 与环己基膦 (PHCy) 反应得到 [RuHCl(CO)L(PHCy)],其在乙腈中用 HX 质子化得到 [RuCl(NCMe)(CO)L( PHCy)]X (X = ClO, OTf, PF) 盐,而 HCl 提供 [RuCl(CO)L(PHCy)]。不稳定的氯化物和/或乙腈配体被 CO、CNCHMe-2,4,6、[EtNCS] 或 [Tp] (Tp = 加氢三(吡唑基)硼酸盐) 取代以提供 [RuCl(CO)L(PHCy)], [Ru[Cl(CO)(CNCHMe-2,4,6)L(PHCy)]、[Ru(SCNEt)(CO)L(PHCy)] 和 [Ru(CO)L(Tp)(PHCy)] 盐。 [RuCl(CO)L(PHCy)]OTf 在苯中去质子化得到 [RuCl(PHCy)(CO)L],但在甲醇中得到仲甲氧基膦络合物 [Ru(CO)LPH(OMe)Cy}]
