A mixture of isomeric aldehydes is formed in a catalytic isomedzation of alkyl aldehydes with [C5Me5Rh(olefin)2] complexes. This process offers an indirect method for altering the n:iso ratio of aldehydes formed in hydroformylation reactions. For example the reaction of n-butanal with [C5Me5Rh(CH2 = CHMe)2] (1) results in the formation of a bis-alkyl carbonyl rhodium complex 2 which is the resting state during the isomerization of n-butanal to a mixture of n- and isobutanals (see scheme). In the presence of other olefins transfer formylation is observed.
