Abstract:
1. A process for the hydroformylation of compounds which comprises, providing at least one compound with an ethylenically unsaturated double bond and reacting the at least one compound with carbon monoxide and hydrogen in at least one reaction zone in the presence of a catalytically active fluid which comprises a dissolved metal complex of a metal of transition group VIII of the Periodic Table of the Elements with at least one phosphoramidite compound as ligand, wherein the fluid is brought into contact with at least one base selected from trialkyl amines, dialkyaryl amines, alkyldiaryl amines, triaryl amines, and bases immobilized on a solid phase, or a combination thereof, and wherein the phosphoramidite compound is selected from among compounds of the formulae I and II where R R Y is a divalent bridged group having from 2 to 20 bridge atoms between the flanking bonds, X a, b, c and d are each, independently of one another, 0 or 1.
