Patent ID: 7550406

Claim:
A catalyst composition comprising a bidentate ligand represented by formula 1, a monodentate ligand represented by formula 2, and a transition metal catalyst represented by formula 3: wherein each of R 1 and R 2 is a substituted or unsubstituted C1-20 alkyl group; a substituted or unsubstituted C1-20 alkoxy group; a substituted or unsubstituted C5-20 cycloalkane or cycloalkene; a substituted or unsubstituted C6-36 aryl group; a substituted or unsubstituted C1-20 heteroalkyl group; a substituted or unsubstituted C4-36 heteroaryl group; or a substituted or unsubstituted C4-36 heterocyclic group, Ar 1 -Ar 2 is a bisaryl compound, and X is oxygen (O) or sulfur (S), wherein each of R 3 , R 4 and R 5 is a substituted or unsubstituted C1-20 alkyl group; a substituted or unsubstituted C1-20 alkoxy group; a substituted or unsubstituted C5-20 cycloalkane or cycloalkene; a substituted or unsubstituted C6-36 aryl group; a substituted or unsubstituted C1-20 heteroalkyl group; a substituted or unsubstituted C4-36 heteroaryl group; or a substituted or unsubstituted C4-36 heterocyclic group, each of R 3 , R 4 and R 5 being optionally substituted with nitro (—NO 2 ), fluorine (F), chlorine (Cl), bromine (Br), or a C1-4 alkyl group, and Y is oxygen (O) or sulfur (S), M(L 1 ) l (L 2 ) m (L 3 ) n (3) wherein M is a transition metal, each of L 1 , L 2 and L 3 is hydrogen, CO, acetylacetonato, cyclooctadiene, norbornene, chlorine, or triphenylphosphine, each of l, m and n is a number of 0 to 5, provided that all l, m and n are not zero simultaneously, wherein the concentration of the transition metal is 50 to 500 ppm based on the amount of the catalyst composition, and the concentration of the bidentate ligand is 0.5 to 20 mol and the concentration of the monodentate ligand is 0.1 to 200 mol, respectively, per mol of the transition metal, wherein the transition metal catalyst is acetylacetonatodicarbonylrhodium (Rh(AcAc)(CO) 2 ), the bidentate ligand is 1,1′-biphenyl-2,2′-diyl-bis(dipyrrolylphosphoramidite) (BPO—P(Pyl) 2 ), and the monodentate ligand is triphenylphosphine oxide (TPPO).
