TRANSITION METAL COMPLEX, PREPARATION METHOD FOR SAID TRANSITION METAL COMPLEX, TRIMERIZATION CATALYST, PREPARATION METHOD FOR 1-HEXENE, PREPARATION METHOD FOR ETHYLENE POLYMER, SUBSTITUTED CYCLOPENTADIENE COMPOUND, AND PREPARATION METHOD FOR SAID SUBSTITUTED CYCLOPENTADIENE COMPOUND

Disclosed is transition metal complex that serves as a catalytic component with which 1-hexene can be produced efficiently with excellent selectivity, even under high temperature conditions, by means of an ethylene trimerization redaction. Also disclosed is a method for economically preparing a butyl-branched ethylene polymer, even under high temperature conditions, by using said transition metal complex as an ethylene trimerization catalyst, and polymerizing ethylene in the presence of an olefin polymerization catalyst that is obtained by bringing an olefin copolymerization catalyst and an activating co-catalytic component into contact with one another. Said transition metal complex is represented by the following general formula (1), wherein M1 represents a Group 4 transition metal atom, and R1 through R11 and X1 through X3 each independently represent a hydrogen atom, a halogen atom, or a specific organic group.

thallium(I) and thallium(I) - Polymeric Organometallic Compounds with Chain Structure

(Dimethylphenylsilyl)tetramethylcyclopentadiene (2) and (benzyldimethylsilyl)tetramethylcyclopentadiene (3) were prepared from (tetramethylcyclopentadienyl)lithium (1) and chlorodimethylphenylsilane or benzylchlorodimethylsilane, respectively. 2 and 3 react with TlOC2H5 (4) to form Tl (5) and Tl (6), respectively.The 1H- and 13C-NMR spectra of the new compounds as well as the single-crystal X-ray structural analyses of the polymeric metallocenes 5 and 6 are described and discussed.
