Complexes possessing a soft donor η6-arene and hard donor acetylacetonate ligand, [(η6-p-cymene)Ru(κ2-O,O-acac-μ-CH)]2[OTf]2 (1) (OTf = trifluoromethanesulfonate; acac = acetylacetonate) and [(η6 - p -cymene) Ru (κ2 - O, O -acac) (THF)] [BAr4′] (2) {Ar′ = 3,5-(CF3)-C6H3}, were prepared and fully characterized. The lability of the μ-CH linkage for complex 1 and the THF ligand of 2 allow access to the unsaturated cation [(η6-p-cymene)Ru(κ2-O,O-acac)]+. The reaction of [(η6 - p -cymene) Ru (κ2 - O, O -acac) (THF)] [BAr4′] (2) with KTp {Tp = hydridotris(pyrazolyl)borate} produces [TpRu (η6 - p -cymene)] [BAr4′] (5). The azide complex [(η6 - p -cymene) Ru (κ2 - O, O -acac) (N3 Ar)] [BAr4′] (6) forms upon reaction of [(η6 - p -cymene) Ru (κ2 - O, O -acac) (THF)] [BAr4′] (2)with N3Ar (Ar = p-tolyl), and reaction of [(η6 - p -cymene) Ru (κ2 - O, O -acac) (THF)] [BAr4′] (2) with CHCl3 at 100 °C yields the chloride-bridged binuclear complex [{(η6 - p -cymene) Ru}2 (μ -Cl)3] [BAr4′] (7). The details of solid-state structures of [(η6-p-cymene)Ru(κ2-O,O-acac-μ-CH)]2[OTf]2 (1), [TpRu (η6 - p -cymene)] [BAr4′] (5) and [{(η6 - p -cymene) Ru}2 (μ -Cl)3] [BAr4′] (7) are disclosed.
