资源简介：
The synthesis and characterization
of 1,2-azaborolyl (Ab)-ligated
titanium(IV) half-metallocene complexes are presented, and their catalytic
properties in ethylene polymerization have been evaluated. Mono-Ab
TiCl3 complexes 3 and 4 can be
conveniently converted to other half-metallocene derivatives (5–8) in moderate to good yields. The molecular
structures of titanium complexes 3–8 have been determined by X-ray diffraction analysis. Upon activation
with methylaluminoxanes (MAO), mono-Ab Ti half-metallocenes demonstrated
high catalytic activity in ethylene polymerization (1.50 × 107 g of PE (mol of Ti)−1 h–1) at a low [MAO] (Al:Ti = 30) .
