ABSTRACT:
A process is disclosed for preparing compounds such as 4-acetoxybutyraldehyde which comprises contacting reactants such as allyl acetates with a cobalt carbonyl catalyst in the presence of various novel promoters. The promoters are selected from the group consisting of triphenyl germane, tetraphenyl germane, phenyl sulfide, succinonitrile and 2,2'-dipyridyl. The reaction is preferably conducted in the presence of a ketone solvent.
