Abstract

The invention relates to a bisphosphite of the formula Iwhere X=a divalent substituted or unsubstituted bisalkylene or bisarylene radical, Y=a divalent substituted or unsubstituted bisarylene or bisalkylene radical, Z=oxygen or NR9, and R1, R2, R3, R4 are identical or different, substituted or unsubstituted, linked, unlinked or fused aryl or heteroaryl radicals and R9 is hydrogen or a substituted or unsubstituted alkyl or aryl radical, a process for preparing it and also the use of this phosphite in catalysis in particular in the catalytic hydroformylation of olefins or organic compounds having C—C double bonds.
