Stoichiometric and catalytic C-F bond activation by the<i> trans</i>-dihydride complex [Ru(IEt<sub>2</sub>Me<sub>2</sub>)<sub>2</sub>(PPh<sub>3</sub>)<sub>2</sub>H<sub>2</sub>] (IEt<sub>2</sub>Me<sub>2</sub> = 1,3-diethyl-4,5-dimethylimidazol-2-ylidene)
The room temperature reaction of C6F6 or C6F5H with [Ru(IEt2Me2)2(PPh3)2H¬2] (1; IEt2Me2 = 1,3-diethyl-4,5-dimethylimidazol-2-ylidene) generated a mixture of the trans-hydride fluoride complex [Ru(IEt2Me2)2(PPh3)2HF] (2) and the...

Room Temperature Regioselective Catalytic Hydrodefluorination of Fluoroarenes with <i>trans</i>-[Ru(NHC)<sub>4</sub>H<sub>2</sub>] Via a Converted Nucleophlic Ru-H Attack Pathway
The efficient and highly selective room temperature hydrodefluorination (HDF) of fluoroarenes by the trans-[Ru(IMe4)4H2] catalyst, 3, is reported. Mechanistic studies show 3 acts directly in catalysis without any ligand...
