Encapsulated transition metal catalysts comprising peripheral Zn(II)salen building blocks: template-controlled reactivity and selectivity in hydroformylation catalysis.

Encapsulated phosphane ligands can be easily constructed through coordinative interactions between Zn(II)-salphen complexes and pyridylphosphane templates; the template has a pronounced impact on the catalyst structure and consequently on the performance in the hydroformylation of 1-octene.
