  Reduction of substituted 1,10-phenanthrolines as a route to rigid chiral benzimidazolylidenes

  摘要：

  Variously substituted 1,10-phenanthrolines are reduced to octahydrophenanthrolines in moderate to good yields with NaBH3CN in acetic acid/methanol. The exact solvent composition is important to avoid the formation of tetrahydrophenanthrolines and N-alkylated by-products, and to optimize the formation of octabydrophenanthrolines. Resolution of a racemic reduction product gives an enantiornerically pure C-2-symmetric diamine from which the corresponding rigid benzimidazolylidene is prepared, whereas reduction of chiral phenanthrolines derived from bicyclic ketones affords diastercomerically pure diamines, which may also be converted to benzimidazolylidenes.

  The present invention relates to a novel Group 4 transition metal compound, a method for preparing the compound, a catalyst composition comprising the compound, and a method for preparing a polyolefin comprising performing a polymerization reaction of olefin monomers, in the presence of the catalyst composition. Since the Group 4 transition metal compound of the present invention exhibits an excellent catalytic activity in polyolefin synthesis reactions, as well as having excellent thermal stability, it can be used for polyolefin synthesis reactions at high temperatures, and by changing the type of a central metal and ligand, the weight average molecular weight of synthesized polyolefins and the octene content in the polymer can be controlled. Therefore, it can be effectively used in polyolefin synthesis processes in which grades are controlled.

  本发明涉及一种新型第 4 族过渡金属化合物、一种制备该化合物的方法、一种包含该化合物的催化剂组合物，以及一种制备聚烯烃的方法，该方法包括在该催化剂组合物存在下进行烯烃单体的聚合反应。 由于本发明的第 4 族过渡金属化合物在聚烯烃合成反应中表现出优异的催化活性，并具有优异的热稳定性，因此可用于高温下的聚烯烃合成反应，而且通过改变中心金属和配体的类型，可控制合成聚烯烃的重量平均分子量和聚合物中的辛烯含量。因此，它可有效地用于控制等级的聚烯烃合成工艺。
