Process for the preparation of aldehydes by hydroformylation of olefins

摘要

Catalytic hydroformylation of 3-24C olefins utilizes a group VIII metal in the presence of a functionalized phosphonite ligand to give high selectivity. Catalytic hydroformylation of 3-24C olefins utilizes a group VIII metal in the presence of a ligand of formula (I). X = As, Sb or P; R<1>a-d and R<2>a-d = H or 1-25C aliphatic or aromatic hydrocarbon or aliphatic or aromatic alkoxy; Q<1>-Q<4> = O, S, NR<7> or CR<7>R<8>; R<7>, R<8> = R<1>a provided that Q<3> or Q<4> is O, S or NR<7>; Y = OR<5>, COOR<5>, COOM, SR<5>, NR<5>R<6>, N=CR<5>R<6>, COR<5>, CONR<5>R<6>, F, Cl, Br or I; R<5> and R<6> = H or 1-25C aliphatic or aromatic hydrocarbon; M = H, Li, Na, K or NH4; Z<1> and Z<2> = 1-75C (un)substituted aliphatic or aromatic hydrocarbon or together form a covalent bond; and m, n, o, p = 0 or 1, provided that either o or p is 1.
