Abstract
A process for making a carbonyl-containing compound is disclosed. In this process an allylic ether is contacted with water in the presence of a cobalt-containing material under an atmosphere of carbon monoxide gas.
Claims27
A process for making a carbonyl-containing compound selected from the group consisting of aldehydes and ketones comprising contacting an allylic ether having the structural formula
- R.sup.1 --CH.dbd.CH--CH(R.sup.3)--OR.sup.2
- where R.sup.1 and R.sup.3 are the same or different and are hydrogen or a cyclic or an acyclic hydrocarbyl group containing up to about 15 carbon atoms which may be substituted with a carboxylate group, a carbonyl group, a nitrile group, an ether group or mixtures thereof;
- and R.sup.2 is a cyclic or acyclic hydrocarbyl group containing up to about 12 carbon atoms with water in the presence of a cobalt-containing material under an atmosphere of carbon monoxide gas whereby a carbonyl-containing compound having the structural formula
- R.sup.1 --CH.sub.2 --CH.sub.2 --CR.sup.3 (0)
- where R.sup.1 and R.sup.3 have the meanings given above is formed.
