Synthesis of zirconium aryloxide complexes containing pendent vinyl groups

The attachment of pendent olefin groups to oxygen-ligated zirconium complex es using olefin-substituted phenols and alcohols and readily accessible zir conium reagents is described. Syntheses of three crystallographically chara cterizable complexes isolable in 55-90% yield are reported. Eugenol, HOC6H3 (OMe-2)(CH2CH=CH2-4) (HOAr) reacts with [Zr((OPr)-Pr-i)(4)((HOPr)-Pr-i)](2) in toluene to form [((PrO)-Pr-i)(2)(ArO)Zr(mu-(OPr)-Pr-i)](2), 1. CH2=CHCH 2OH reacts with [Zr(NMe2)(4)](2) in the presence of 2,6-dimethylphenol to f orm the mixed ligand salt, {Me2NH2}{[(2,6-Me2C6H3O)(3)Zr](2)(mu-OCH2CH=CH2) (3)}, 2. The potassium salt derived from eugenol, KOAr, reacts with "Zr(OEt )(4)" in THF to form [K2Zr(OAr)(4)(OEt)](2)(O), 3.
