Abstract

A process for the preparation of carbonyl compounds by catalyzed isomerization of allyl alcohols in a tertiary phosphine or phosphite ester in the presence of a rhodium compound at a temperature of from 80.degree. C. to 180.degree. C., a carrier gas being passed through the reaction mixture and the carbonyl compound being separated from the emergent gas mixture by cooling.
