摘要: 以三烷基钪Sc(CH₂SiMe₃)₃(THF)₂和胺基膦亚胺配体为原料,经烷基消去反应合成了亚胺膦亚胺(NPN)型配体螯合钪烷基配合物。其结构用¹H NMR、¹³C NMR、元素分析和X射线衍射分析进行了表征。在助催化剂有机硼盐和烷基铝的作用下,该配合物对丁二烯聚合表现出了较高的催化活性。并且随着聚合温度的降低,催化剂的1,2-选择性也随之升高。聚合温度为-75℃时,产物的1,2-结构含量高达98.0%,聚合物的分子量为2.95×10⁴,分子量分布为1.65。

Abstract: Treatment of scandium tris(alkyl)s,Sc(CH₂SiMe₃)₃(THF)₂,with 2-Me-C₆H₄NHPPh₂=NC₆H₂-2,4,6-Me₃(NPN^ArH) via deprotonation affords the bis(alkyl) derivative [NPN^Ar]Sc(CH₂SiMe₃)₂(THF).The complex structure was characterized by means of ¹H NMR,¹³C NMR,elemental analysis and X-ray diffraction analysis.Complex activated with [Ph₃C][B(C₆F₅)₄] and AliBu₃ exhibited highly catalytic activity to the polymerization of butadiene.The 1,2-selectivity of polybutadiene noticeably increased with decrease of temperature.The molecular mass is 2.95×10⁴ and the molecular mass distribution(M_w/M_n) is 1.65 at-75℃.
