Abstract

.alpha.-alkyl aldehydes having 8 to 17 carbon atoms are obtained from terminal olefins containing one less carbon atom. The olefins are first isomerized in the presence of iron carbonyl and then, without separating out the iron compound, hydroformylated in the presence of rhodium as catalyst.
