摘要：

The cyclopentadienyl(beta-diketiminato)titanium and zirconium chlorides (eta(5),C5H5)MCl2(CH(C(NC6H4-4-OR)CH3)(2)) (M = Ti (4-dend), Zr (5-dend)), where R corresponds to the first generation carbosilane dendron (dendritic wedge) Si(CH2CH2SiMePh2)(3), have been synthesised. After activation with methylaluminoxane, the activity of 4-dend and 5-dend as catalysts for ethylene polymerisation has been determined and compared with that of the non-dedritic counterpart (eta(5)-C5H5)MCl2CH(C(NC6H5)CH3)(2)) (M=Ti (4), Zr (5)).
