Ruthenium(II) complexes possessing the η6-p-cymene ligand

摘要: Complexes possessing a soft donor η 6 -arene and hard acetylacetonate ligand, [(η -p-cymene)Ru(K2-0,0-acac-μ-CH)] 2 [OTf] (1) (OTf=trifluoromethanesulfonate; acac = acetylacetonate) -p-cymene)Ru(κ -0,0-acac) (THF)] [BAr' 4 ,] (2) {Ar'= 3,5-(CF 3 )-C H }, were prepared fully characterized. The lability of the μ-CH linkage for complex 1 THF ligand allow access to unsaturated cation -p-cymene)Ru(K2-O,O-acac)]+. reaction -p-cymene)Ru(K2-0,0-acac) (THF)][BAr' ] with KTp {T p hydridotris(pyrazolyl)borate} produces [TpRu(η -p-cymene)][BA' (5). azide (N Ar)][BAr' (6) forms upon -O, O-acac)(THF)][BAr' (2)with N Ar (Ar p-tolyl), -p-cymene)Ru(K2-O,O-acac)(THF)][BAr' CHCl at 100 °C yields chloride-bridged binuclear [{(η -p-cymene)Ru}2(μ-Cl)3][BAr4] (7). details solid-state structures -p-cymene)Ru(K2-O,O-acac-μ-CH)]2[OTf]2 (1), -p-cymene)][BAr' (5) -p-cymene)Ru} (μ-Cl) ][BAr' (7) are disclosed.
