Catalyst composition comprising phosphine ligands and Hydroformylation reaction using the same

摘要

A catalyst composition comprising phosphorous compounds and a hydroformylation reaction using the same are provided to adjust an N/I selectivity to a range from 1 to 30 by controlling the ratio of the two ligands while showing a high catalytic activity. A catalyst composition comprises: (a) a bidentate ligand represented by a formula 1; (b) a bidentate ligand represented by a formula 2; and (c) a transition metal catalyst, wherein in the formula 1, R1 and R2 each denote a substituted or non-substituted monovalent hydrocarbon group capable of comprising at least one hetero atom selected from nitrogen, oxygen and sulfur atoms, Ar1 and Ar2 each denote arylene, R3s each independently denote hydrogen, -R14, -OR14, Si(R14)3, -Si(OR14)3, -C(O)R14, -C(O)OR14, -OC(O)R14, -C(O)N(R14)2, -S(O)2R14, -S(O)R14, -SR14, -N(R15)2, -N(R15)C(O)R15, -P(O)(R15)2, halogen, nitro, cyano, or hydroxy, where each of R14s independently denotes C1-C20-alkyl, C6-C20-aryl, C1-C20-alk-C6-C20-aryl, and C6-C20-ar-C1-C20-alkyl, each of R14s independently denotes hydrogen, C1-C20-alkyl, C6-C20-aryl, C1-C20-alk-C6-C20-aryl, and C6-C20-ar-C1-C20-alkyl, and each of R15s independently denotes hydrogen, C1-C20-alkyl, C6-C20-aryl, C1-C20-alk-C6-C20-aryl, and C6-C20-ar-C1-C20-alkyl, and wherein in the formula 2, Ar3s are identical to or different from one another and each denote a substituted or non-substituted C6-C20-arylene, W denotes a C2-C30 m-valent radical selected from the group consisting of alkylene, alkylene-oxy-alkylene, arylene and arylene-(CH2)y-(Q)n-(CH2)y-arylene, where each arylene is identical to the defined Ar3, y has a value of 0 or 1, and Q each independently denotes a bivalent connecting group selected from the group consisting of a single bond, -CR^16R^17-, -O-, -S-, -NR^18-, -SiR^19R^20- and -CO-, where R^16 and R^17 each independently denote a radical selected from the group consisting of hydrogen, C1-C12-alkyl, phenyl, tolyl and anicyl, R^18, R^19 and R^20 radicals each independently denote -H or -CH, n each has a value of 0 or 1, and m has a value of 2 to 6.
