A catalyst for the hydroformylation of at least one olefin, having a ligand fo the general formula (1) &#x2014;R, R, Rselected from the group including substituted and non-substituted alkyl, substituted and non-substituted aryl, substituted and non-substituted alkenyl, substituted and non-substituted alkinyl, substituted and non-substituted cycloalkyl, and substituted and non-substituted heterocycles, wherein R, Rand Rcan each be the same or different, L is selected from a group having a sandwich complex, an oxygen group, substituted and non-substituted alkylene or heterocycles, and substituted aryl or heteroaryl; and aryl and heteroaryl is each substituted with groups which contain at least two heteroatoms and are coupled to the Si via the at least two heteroatoms of the substituents, &#x2014;n=1-10, preferably 1-5, particularly preferably 1, 2, or 3; and the ligand is coupled to the metal M from the group VIIIb of the periodic table of elements via the Si group.

Catalyst for the hydroformylation of olefins, and use thereof

This invention relates to a process for the catalytic hydroformylation of olefins by reaction of an olefin with hydrogen and carbon monoxide in a liquid, aqueous-organic reaction medium in the presence of a water-soluble hydroformylation catalyst, characterized in that for a substantial period of the hydroformylation reaction, the aqueous-organic medium is present in the form of a microemulsion, which is made up of an oil phase containing the olefin or the olefin and its hydroformylation products, an aqueous phase containing the water-soluble complex catalyst, and a nonionic surfactant.
