Abstract
Treatment of Li{CH(SiMe3)Ar}(tmeda) (Ar = 9-anthryl, tmeda = Me2N[CH2]2NMe2) with zirconocene(1v) chloride in tetrahydrofuran at 20 °C affords [Zr{CH(SiMe3)Ar}CI(ŋ-C5H5)2],which rapidly reacts with carbon monoxide (Pco 1 atm, 20 °C) in toluene to afford exclusively the E-metallo-enolate [Zr{OC(SiMe3)=CHAr}CI(ŋ-C5H5)2], having Zr-0 1.950(4) Å and < Zr-O-C 157.7(3)°.
