| 英文摘要 | A series of novel phenoxy-phosphinimine ligands (l): l = 2-(ph2p=nr), 4, 6-(cme3)(2)-c6h2oh [2, r = sime3; 3, r = ph] have been prepared in the yield of 65-71%. and bis(phenoxy-phosphinimide) group 4 complexes of the type l2mcl2 [4, m = ti, r = sime3; 5, m = zr, r = sime3; 6, m = ti, r = ph; 7, m = zr, r = ph] have been synthesized by the reaction of the ligands with ticl4 and zrcl4. the structure of complex 7 has been determined by x-ray crystallography. the complexes 4-7 showed inactive to ethylene polymerization in the presence of modified methylaluminoxane (mmao) and i-bu3al/ph3cb(c-6 f-5)(4). these results should be caused by overdoing the steric congestion around central metal.
