摘要
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, HOC(6)H(3)(OMe-2)(CH(2)CH=CH(2)-4) (HOAr) reacts with [Zr(O(i)Pr)(4)(HO(i)Pr)](2) in toluene to form [((i)PrO)(2)(ArO)Zr(&mgr;-O(i)Pr)](2), 1. CH(2)=CHCH(2)OH reacts with [Zr(NMe(2))(4)](2) in the presence of 2,6-dimethylphenol to form the mixed ligand salt, {Me(2)NH(2)}{[(2,6-Me(2)C(6)H(3)O)(3)Zr](2)(&mgr;-OCH(2)CH=CH(2))(3)}, 2. The potassium salt derived from eugenol, KOAr, reacts with Zr(OEt)(4) in THF to form [K(2)Zr(OAr)(4)(OEt)](2)(O), 3.
