[54] METHOD FOR PRODUCING THE TRANSITION METAL COMPLEX, CATALYST FOR TRIMERIZATION, METHOD FORPRODUCING 1-HEXENE, METHOD FOR PRODUCING THE SUBSTITUTED CYCLOPENTADIENE COMPOUND ‎‎1‎
[57] Abstract: An object of the present invention is to provide a silicon-bridged Cp-Ar transition metal complex ‎that serves as a catalytic component capable of efficiently and highly selectively producing 1-‎hexene through the trimerization reaction of ethylene. The present invention provides a ‎transition metal complex represented by formula (1):‎ wherein M1 represents a transition metal atom of Group 4 of the Periodic Table of the Elements; ‎X1, X2, X3, R1, R2, R3 and R4 each independently represent a hydrogen atom or the like; Ar1 is an ‎aryl group represented by formula (2), Ar2 is an aryl group represented by formula (3) and Ar3 is ‎an aryl group represented by formula (4) (not all of the three aryl groups Ar1, Ar2 and Ar3 are the ‎same at the same time),‎ R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18 and R19 each independently represent‎a hydrogen atom or the like.‎
