Inorganic chemistry, 38(6), 1160-1164 (2001-10-24)
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)
