  The present invention provides a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a method for synthesizing the complex, and olefin polymerization using the same. The method for preparing a transition metal complex according to the present invention comprises a step of blocking a by-reaction of a nitrogen atom using a compound containing a protecting group, and thus it is possible to prepare a transition metal complex in a simpler manner in a high yield. Further, the transition metal complex according to the present invention has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, sterically monomers can easily approach the transition metal complex.

  本发明提供了一种新型过渡金属配合物，其中配位了一个含有氨基团的单环戊二烯基配体，以及一种合成该配合物的方法，以及使用该配合物进行烯烃聚合的方法。根据本发明的制备过渡金属配合物的方法包括通过使用含有保护基团的化合物阻止氮原子的副反应的步骤，因此可以以更简单的方式高产率地制备过渡金属配合物。此外，根据本发明的过渡金属配合物具有一个五角形环结构，其中通过苯桥连接的氨基团与金属位点附近形成了稳定的键，因此，立体构型的单体可以轻松接近过渡金属配合物。

  The present invention provides a novel transition metal complex where a monocy-clopentadienyl ligand to which an amido group is introduced is coordinated, a method for synthesizing the complex, and olefin polymerization using the same. The method for preparing a transition metal complex according to the present invention comprises a step of blocking a by-reaction of a nitrogen atom using a compound containing a protecting group, and thus it is possible to prepare a transition metal complex in a simpler manner in a high yield. Further, the transition metal complex according to the present invention has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, sterically monomers can easily approach the transition metal complex. When a catalyst composition comprising the transition metal complex is applied in copoly-merization of ethylene and monomers having large steric hindrance, a very low density polyolefin copolymer having a density of less than 0.910 g/cc, in addition to a polyolefin having a high molecular weight and a linear low density, can be prepared. Furthermore, the reactivity is also very high.
