英文摘要	(Phosphinoamide)(cyclopentadienyl)titanium(IV) complexes of the type CpTiCl2 (eta(2)-Ph2PNR) [CP=C5Me5; R = t-Bu (2a), R = n-Bu (2b), R = Ph (2c)] have been prepared by the reaction of CpTiCl3 with the corresponding lithium phosphinoamides. The structure of CpTiCl2(eta(2) -(Ph2PNBu)-Bu-t) (2a) and Cp*TiCl2(eta(2) -Ph2PNPh) (2c) have been determined by X-ray crystallography. These complexes exhibited moderate catalytic activities for ethylene polymerization in the presence of modified methylaluminoxane (MMAO). Catalytic activity of up to 2.5 x 10(6) g/(mol Ti h) was observed when activated by i-Bu3Al/Ph3CB(C6F5)(4). (c) 2005 Elsevier B.V. All rights reserved.
