BISPHOSPHITE MIXTURE AND USE THEREOF AS A CATALYST MIXTURE IN HYDROFORMYLATION

摘要

The invention relates to a mixture of bisphosphites, to a process for preparation thereof, and to the reaction thereof with metals to give mixtures comprising complexes of the constitutionally isomeric bisphosphites and the metal, and to the use thereof as a catalytically active composition in hydroformylation reactions, and also to the hydroformylation reaction itself.

主权项

1. A mixture comprising the compounds (Ia) and (IIa):where
R1 is selected from —Me, -tBu, —OMe; R2 is selected from —Me, -tBu, —OMe; R3 is selected from —Me, -tBu, —OMe; R4 is selected from —Me, -tBu, —OMe; with the proviso that, if R1 is the same as R3, R2 is not the same as R4, if R2 is the same as R4, R1 is not the same as R3, and P can enter into further bonds.
