PROCESS FOR PREPARING ALDEHYDES SUBSTITUTED IN THE .ALPHA. POSITION BY AN ALKYL RADICAL

摘要

Aldehydes having from 8 to 17 carbon atoms in the molecule and substituted in the .alpha. position by an alkyl radical are obtained from the terminal olefins containing one less carbon atom. For this purpose, the olefins are first isomerized in the presence of iron carbonyl and then, without separating off the iron compound, hydro-formylated in the presence of rhodium as catalyst.
