The metal-catalyzed isomerization−hydroformylation tandem reaction is of great importance for the production of linear aldehydes starting from internal olefins, but also, the shift of the double bond from a terminal position into the interior of an alkyl chain and the subsequent hydroformylation can be of interest. This review aims to summarize problems and achievements in this area under particular consideration of results published by the Leibniz-Institut fur Katalyse (LIKAT) in the past two decades. A main focus is given to the variation of metals (Co, Rh, Ru, Pd, Pt, Fe) and phosphorus ligands used for the tandem reaction.
