Abstract
The invention relates to mixtures of constitutional isomer bisphosphites of formulae (1a) and (2a), to a method for the production thereof, to the reaction thereof with metals to form mixtures containing complex compounds of the constitutional isomer bisphosphites of formulae (1a) and (2a) and the metal, and to the use thereof as a catalytically active composition in hydroformylation reactions. Said hydroformylactically active compositions comprises, in addition to the complex compounds of metal and the constitutional isomer bisphosphites of formulae (1a) and (2a), non-bound bisphosphites of the constitutional isomer bisphosphites of formulae (1a) and (2a) and at least one additional component.
