Abstract:
The invention relates to bisphosphites having 2,4-tert-butylphenyl units and a method for the preparation thereof. Furthermore, the invention relates to the use of the compounds as ligands in a ligand-metal complex. The compound, and also the complex, may be used as a catalytically active composition in hydroformylation reactions.
