A series of novel phenoxy-phosphinimine ligands (L): L = 2-(Ph2PNR), 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
一系列新的苯氧基-膦亚胺配体(L):L = 2-(Ph 2 PNR),4,6-(CMe 3)2 -C 6 H 2 OH [ 2,R = SiMe 3;R = SiMe 3。3,R = Ph]的制备产率为65-71%。L 2 MCl 2 [ 4,M = Ti,R = SiMe 3 ; 5,M = Zr,R = SiMe 3;M = Zr,R = SiMe 3。6,M = Ti,R = Ph;由图7可见,通过配体与TiCl 4和ZrCl 4的反应合成了M = Zr,R = Ph]。。配合物7的结构已经通过X射线晶体学确定。配合物4 - 7在改性的甲基的存在(MMAO),并表现出惰性乙烯聚合我-Bu 3的Al /植3 CB(C 6 ˚F 5)4。这些结果应该是由于过度消耗中心金属周围的空间拥堵引起的。
