Phosphorus-containing catalyst composition and hydroformylation process using the same

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 R1 and R2 is a substituted or unsubstituted C4-36 heteroaryl group,
• Ar1-Ar2 is a bisaryl compound, and
• X is oxygen (O),
• wherein the bisaryl compound Ar1-Ar2 is represented by either formula 5 or formula 6:
• wherein
• each of R8, R9, R10, and R11 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 —CO2R (wherein R is a C1-20 alkyl group or a C6-20 aryl group),
• wherein
• each of R12, R13, R14, R15, R16, and R17 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 —CO2R (wherein R is a C1-20 alkyl group or a C6-20 aryl group),
• wherein
• each of R3, R4 and R5 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 R3, R4 and R5 being optionally substituted with nitro (—NO2), fluorine (F), chlorine (Cl), bromine (Br), or a C1-4 alkyl group,
• M(L1)l(L2)m(L3)n (3)
• wherein
• M is rhodium,
• each of L1, L2 and L3 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.
