Dehydroformylation of isomeric acetoxybutyraldehydes, with minimal dehydroacetoxylation, can be accomplished at a temperature in the range of 120 DEG -250 DEG C. in a nonoxidizing atmosphere in the presence of an essentially neutral noble metal catalyst to produce allyl acetate, 1-propenyl acetate or mixtures thereof. This reaction permits recycle of the undesired isomeric acetoxybutyraldehyde products of the hydroformylation of allyl acetate of 1-propenyl acetate to the desired 4-acetoxybutyraldehyde which is an intermediate in the production of 1,4-butanediol useful in making polyesters.
