Several trialkoxy(2-butenyl)zirconium(IV)6,7i 18 and 2-butenylbis(cyclopentadienyl)zirco-nium(IV)18,19 124 complexes have been investigated with respect to the diastereoselectivity on addition to aldehydes. Chlorobis(cyclopentadienyl)-(3-tributylstannyl-2-propenyl)zirconium(IV), prepared by hydrozirconation of tributyl-(l,2-propadienyl)tin, accomplishes the (E)-selective, Wittig-like 1,2-propenylidenation of aldehydes and methyl ketones125.

In contrast, aldol condensation with (Z)- and (E)-chlorobis(cyclopenladienyl)-zirconium enolates results in ery/Iiro-diastereoselection regardless of the geometry of the enolate.2 3 These enolates are prepared from lithium enolates by metal exchange with Cp,ZrCl, at —78°. The effect is particularly marked with amide enolates (equation II). [Pg.70]

Reductive alkylation takes place when l,l-bromo-2-methyl-2-phenylcyclopropane is treated with an alkyllithium reagent followed by either chlorobis(cyclopentadienyl)octylzirconium or chlorobis(cyclopentadienyl)[(ii)-octen-l-yl]zirconium. The products 9 and 10 are formed stereoselectively with predominance (95%) of the trans-isomer in both cases. [Pg.1392]

Alkylidene-bridged zirconium complexes 53, long-chain alkylidene analogues of the Tebbe reagent 3, are prepared by the reaction of chlorobis(cydopentadienyl)-(vinyl)zirconium with DIBAL-H, or by addition of the Schwartz reagent, H(Cl)ZrCp2 [116], to a solution of (vinyl)diisobutylaluminum (Scheme 4.49) [117]. Similarly to the Tebbe reagent 3, the complex 53a (R = Bu) itself serves as an... [Pg.185]
