RESOLUTION METHOD FOR A RACEMIC MIXTURE OF ALDEHYDES

摘要

The invention concerns a resolution method for a racemic mixture of aldehyde of formula (I) wherein: R1, R2, R3, R4, R5, R6 Z and n are as defined in Claim (1). The aldehydes of formula I are useful in their enantiomeric form or their racemic form for preparing transition metal complexes useful as catalysts in hydroformylation reactions of olefins.
