Patent

CA 2349918

The invention concerns a resolution method for a racemic mixture of aldehyde of formula (I) wherein: R¿1?, R¿2?, R¿3?, R¿4?, R¿5?, R¿6? 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.

La présente invention concerne un procédé de dédoublement d'un mélange racémique de l'aldéhyde de formule (I): dans laquelle R1, R2, R3, R4, R5, R6, Z et n sont tels que définis à la revendication (1). Les aldéhydes de formule (I) sont utiles sous la forme de l'un de leurs énantiomères ou sous la forme de racémiques pour la préparation de complexes de métaux de transition utilisables comme catalyseurs dans les réactions d'hydroformylation des oléfines.
