A divalent heteroleptic lanthanoid fluoride complex stabilised by the tetraphenylcyclopentadienyl ligand, arising from C–F activation of pentafluorobenzene†
Abstract
The divalent heteroleptic lanthanoid fluoride complex, [Yb(C5Ph4H)(μ-F)(thf)2]2, as well as [Yb(C5Ph4H)2(thf)] and [Yb(C5Ph4H)(C6F5)(thf)2] were obtained from reactions of ytterbium metal with Hg(C6F5)2 and tetraphenylcyclopentadiene under different conditions, and C–F activation of C6F5H by Yb metal was observed.
