Highly branched‐selective hydroformylation of propene is an industrially important transformation, which now can be achieved using a novel caged rhodium catalyst. The catalyst encapsulation is based on a ligand‐template approach in which the second coordination sphere around the encapsulated catalyst is generated by coordination of the catalyst's ligand to Zn II ‐porpholactone moieties surrounding it. As the Zn II ‐porpholactone binds more strongly than the previously used Zn II ‐TPP analogue, the hydroformylation reaction can now also be carried out in polar solvents. More information can be found in the Full Paper by J. N. H. Reek et al. on page 14769.
