- Abstract
- The reaction of LAIMeOH [L = CH(N(Ar)(CMe))(2), Ar = 2,6-i-Pr2C6H3] with CpTiMe3, Cp TiMe3, and Cp ZrMe3 was investigated to yield LAIMe(mu-O)TiMe2CP (2), LAIMe(mu-O)TiMe2CP (3), and LAIMe(mu-O)ZrMe2CP (4), respectively. The resulting compounds 2-4 are stable at elevated temperatures, in contrast to their precursors such as CpTiMe3 and Cp ZrMe3, which already decompose below room temperature. Compounds 2-4 were characterized by single-crystal X-ray structural analysis. Compounds 2 and 3 were tested for ethylene polymerization in the presence of methylaluminoxane. The half-metallocene complex 3 has higher activity compared to 2. The polydispersities are in the range from 2.8 to 4.2. A copolymerization with styrene was not observed.
