Synthesis of zirconium aryloxide complexes containing pendent vinyl groups
The attachment of pendent olefin groups to oxygen-ligated zirconium complexes using olefin-substituted phenols and alcohols and readily accessible zirconium reagents is described. Syntheses of three crystallographically characterizable 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=CHCH2OH reacts with [Zr(NMe2)(4)](2) in the presence of 2,6-dimethylphenol to form 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.
