Patent ID: 8524628

Claim:
A catalyst composition for hydroformylating an alpha-olefin compound 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 C4-36 heteroaryl group, Ar 1 -Ar 2 is a bisaryl compound, and X is oxygen (O), wherein the bisaryl compound Ar 1 -Ar 2 is represented by either formula 5 or formula 6: wherein each of R 8 , R 9 , R 10 , and R 11 is hydrogen, a C1-20 alkyl group, a C6-20 aryl group, a triarylsilyl group, a trialkylsilyl group, a carboalkoxy group, a carboaryloxy group, an aryloxy group, an alkoxy group, an alkylcarbonyl group, an arylcarbonyl group, an amide group, a halogen atom, or a nitrile group, the carboalkoxy group being represented by —CO 2 R (wherein R is a C1-20 alkyl group or a C6-20 aryl group), wherein each of R 12 , R 13 , R 14 , R 15 , R 16 , and R 17 is hydrogen, a C1-20 alkyl group, a C6-20 aryl group, a triarylsilyl group, a trialkylsilyl group, a carboalkoxy group, a carboaryloxy group, an aryloxy group, an alkoxy group, an alkylcarbonyl group, an arylcarbonyl group, an amide group, a halogen atom, or a nitrile group, the carboalkoxy group being represented by —CO 2 R (wherein R is a C1-20 alkyl group or a C6-20 aryl group), wherein each of R 3 , R 4 and R 5 is a substituted or unsubstituted C1-20 alkoxy group; a phenoxy 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, M(L 1 ) l (L 2 ) m (L 3 ) n (3) wherein M is rhodium, each of L 1 , L 2 and L 3 is hydrogen, CO, acetylacetonato, cyclooctadiene, norbornene, chlorine, or triphenylphosphine, and each of l, m and n is a number of 0 to 5, provided that all l, m and n are not zero simultaneously; and wherein the concentration of rhodium is 50 to 500 ppm based on the amount of the catalyst composition, and per mole of the rhodium, the concentration of the monodentate ligand is 0.1 to 10 mol and the concentration of the bidentate ligand is 0.5 to 2 moles to give a N/I selectivity of 2 to 3, or 3 to 10 moles to give a N/I selectivity of 15 to 18.
