    摘要： The present invention provides a novel mononuclear transition metal compound, a novel binuclear transition metal compound, a novel organic amine or phosphorous compound, and a method for preparing the same. The mononuclear transition metal compound according to the present invention is configured such that a cyclopentadienyl group and an amido or phosphorous group are bridged via a phenylene bridge. The binuclear transition metal compound according to the present invention is configured such that the two bridged mononuclear transition metal compounds configured such that a cyclopentadienyl group and an amido or phosphorous group are bridged via a phenylene bridge are linked via a bridging group located at the phenylene bridge. According to the present invention, the mononuclear transition metal compound, the binuclear transition metal compound, the organic amine or phosphorous compound can be prepared in a simple manner by using suzuki-coupling reaction with a high yield.

    摘要： 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.
