Abstract
Allyl alcohol is reacted with carbon monoxide in the presence of a catalytically effective amount of a heterogeneous catalyst composition comprising zero valent palladium and a catalyst promoting amount of hydrogen halide to provide a mixture of products predominantly made up of carboxylic acids containing four and five carbon atoms, e.g., 3-butenoic acid, crotonic acid, butyric acid, isobutyric acid, glutaric acid and methyl succinic acid and possibly minor amounts of other oxygenated compounds such as allyl ether and allyl 3-butenoate.
