A process for Pd-catalyzed hydroxycarbonylation of diisobutene in an acetic acid solvent in the presence of a ligand having the following structure: ##STR00001##
In contrast to reaction solvents such as formic acid or 3,5,5 hexanoic acid the conversion rates were improved and greater than 90% at a reaction temperature of 120 C. and CO pressure of 40 bar.
