摘要

PROBLEM TO BE SOLVED: To provide a transition metal complex used as a component of a catalyst.;SOLUTION: This transition metal complex is expressed by formula (I) [M is a group 4 transition metal; A is a group 16 element; B is a group 14 element; R¹, R², R³, and R⁴ are each selected from a group (I) comprising H, an alkyl, an arkyl, an aralkyl, a substituted silyl, an alkoxy or the like and a group (II) comprising a thio which is substituted by a 1-20C substituted or unsubstituted hydrocarbon group; H, an alkyl, an aryl, an aralkyl, a substituted silyl, an alkoxy or the like, provided that at least one of R¹, R², R³, and R⁴ is selected from the group (II), and any two of R¹, R², R³, and R⁴ which are adjacent to each other may arbitrarily combine with each other to form a ring; R⁵, R⁶, R⁷, R⁸, R⁹, and R¹⁰ are each H, a halogen, an alkyl, an alkoxy or the like, provided that any two of R⁵, R⁶, R⁷, R⁸, R⁹, and R¹⁰ which are adjacent to each other may arbitrarily combine with each other to form a ring; and ; X¹ and X² are each H, a halogen, an alkyl or the like; and n is 0 or 1].;COPYRIGHT: (C)2004,JPO&NCIPI
