Construction of ortho-Phenylene-Bridged Cp/Amido Titanium Complexes by Suzuki-Coupling Reaction and Their Ethylene/1-Hexene Copolymerization |
초록 |
A new synthetic route was devised by using the Suzuki-coupling to prepare ortho-phenylene-bridged Cp/amido titanium complexes. The key starting material in this route, boronic acid 1 can be prepared in 30g-scale. The boronic acid is excellent substrates for the Suzuki-coupling reaction and the cyclopentenone compounds 2 are afforded in excellent yields. The cyclopentenone compounds can be easily transformed to the cyclopentadiene compounds 3 from which various ortho-phenylene-bridged Cp/amido titanium complexes are prepared. Several complexes were characterized by X-ray crystallography and some of them show higher activity, higher incorporation of 1-hexetene, and higher molecular weights than the standard CGC [(5-Me4Cp)CH2CH2(NtBu)]TiCl2. |
