A process for the catalytic hydroformylation of olefins having from 3 to 24 carbon atoms, where the catalyst used comprises a metal of transition group 8 of the Periodic Table in the presence of a ligand represented by formula I: n n n wherein n X=As, Sb, P; n R 1 a-d , R 2 a-d =H, aliphatic or aromatic hydrocarbon radical, aliphatic or aromatic alkoxy group, in each case having from 1 to 25 carbon atoms, where R 1 a-d and R 2 a-d can each be identical or different; n Q 1 , Q 2 , Q 3 , Q 4 =O, S, NR 7 , CR 7 R 8 , where R 7 and R 8 can be identical or different and can have one of the meanings of R 1 a , n, m, o, p=0 or 1, with the proviso that either o or p is 1; n Y=—O—R 5 , —COOR 5 , —COOM, —SR 5 , —NR 5 R 6 , —N═CR 5 R 6 —COR 5 , —CONR 5 R 6 , —F, —Cl—Br, —I, where R 5 and R 6 can be identical or different and are H, an aliphatic or aromatic hydrocarbon radical having from 1 to 25 carbon atoms and M=H, Li, Na, K or NH 4 ; and n Z 1 , Z 2 =substituted or unsubstituted aliphatic or aromatic hydrocarbon radical having from 1 to 75 carbon atoms, where Z 1 and Z 2 may be covalently linked. |
