Reaction of YbCp2(DME) (Cp=cyclopentadienyl; DME=1,2-dimethoxyethane) with perfluorodecalin or perfluoro(methylcyclohexane) in THF yields [YbCp2F(THF)]2. These are the first examples of C-F activation of saturated perfluorocarbons by a lanthanoid organometallic. The X-ray crystal structure of [YbCp2F(THF)]2 (monoclinic, P21/c, a=7.9901(12), b=20.411(4), c=8.5957(12) Å; β=104.70(2)°, Z=2, R1=0.0495, for 1107 observed data) shows the complex to be dimeric with bridging fluorides and formal nine coordination for ytterbium. YbCp2F has also been obtained by oxidation of YbCp2(DME) with AgF or HgF2.
