Claim:
A catalyst composition comprising: (a) a bidentate ligand represented by formula 1 below; and (b) a transition metal catalyst represented by formula 2 below: wherein, R 1 and R 2 are each a substituted or unsubstituted alkyl group of 1-20 carbon atoms, a substituted or unsubstituted alkoxy group of 1-20 carbon atoms, a substituted or unsubstituted cycloalkane or cycloalkene of 5-20 carbon atoms, a substituted or unsubstituted aryl group of 6-36 carbon atoms, a substituted or unsubstituted heteroalkyl group of 1-20 carbon atoms, a substituted or unsubstituted heteroaryl group of 4-36 carbon atoms, or a substituted or unsubstituted hetero ring group of 4-36 carbon atoms; Ar 1 —Ar 2 is a bisaryl compound, wherein the bisaryl compound of the bidentate ligand represented by formula 1 is a compound represented by formula 5 below: wherein, R 6 , R 7 , R 8 , and R 9 are each hydrogen, an alkyl group of 1-20 carbon atoms, an aryl group of 6-20 carbon atoms, a triarylsilyl group, trialkylsilyl group, a carboalkoxy group represented by —CO 2 R where R is an alkyl group of 1-20 carbon atoms or an aryl group of 6-20 carbon atoms, a carboaryloxy group, an aryloxy group, an alkoxy group, an alkylcarbonyl group, an arylcarbonyl group, an amide, a halogen, or a nitrile group; and R 3 is an alkyl group of 1-20 carbon atoms, an aryl group of 6-20 carbon atoms, a triarylsilyl group, a trialkylsilyl group, a carboalkoxy group represented by —CO 2 R where R is an alkyl group of 1-20 carbon atoms or an aryl group of 6-20 carbon atoms, a carboaryloxy group, an aryloxy group, an alkoxy group, an alkylcarbonyl group, an arylcarbonyl group, an amide, a halogen, or a nitrile group, and M(L 1 ) l (L 2 ) m (L 3 ) n (2) wherein, M is a transition metal; L 1 , L 2 and L 3 are each hydrogen, CO, acctylacetonato, cyclooctadiene, norbornene, chlorine, or triphenylphosphine; and l, m, and n are each an integer of 0 to 5, and the sum of l, m and n is not zero.
