摘要: The method for producing .alpha.,.omega.-dialdehydes from .alpha.,.omega.-diolefins or .alpha.,.omega.-alkenals in good yield and with high efficiency. The expensive rhodium catalyst for hydroformylation can be reused without any substantial attrition of activity. Moreover, since the loses of the catalyst, monodentate phosphine and sulfolane used in the hydroformylation reaction are minimal, the method is commercially advantageous.
