A zirconium hydride enolate from carbonylation of the alkyl compound [Zr{C5H2(SiMe3)3-1,2,4}2(Me)2]
Abstract
Reaction of the hindered, substituted electron-withdrawing cyclopentadienyl zirconium complex [Zr{C5H2(SiMe3)3}2(Me)2] with CO leads, via the acyl intermediate [Zr{C5H2(SiMe3)3}2(COMe)(Me)] detected during the course of the reaction, to the metal hydride enolate [Zr{C5H2(SiMe3)3}2(H){OC(Me)CH2}].
