A ligand-splitting transmetalation: The ansa-metalloacenes [(η5 -C12 H8 )2 M(thf)2 ] (M=Yb, Ca) react with ZrCl4 or Me3 SiCl unexpectedly by splitting the ansa-bisacenyl ligand, leading to the formation of the zirconacycle [(η2 -C12 H8 )ZrCl2 (thf)3 ] (1) [Eq. (1)] and the 1,2-bistrimethylsilylacenaphthene (Me3 Si)C12 H8 , respectively.
