Umicore Precatalysts for Asymmetric and Cross-Coupling Catalysis

Efficient and Selective Catalysts for Asymmetric Synthesis

Chloro(1,5-cyclooctadiene)rhodium(I) dimer ([Rh(COD)Cl]₂) can be:

• Employed for the synthesis of rhodium complex of heterocyclic carbenes (NHCs).
• Modified and coated on the surface of ferrite magnetic nanoparticles for catalyzing hydroformylation reaction of olefins.
• Used for the synthesis of triple-layer structure to be used as a ring-opening polymerization catalyst.
• As an effective catalyst for dehydrogenation of amine-borane adducts (hydrogen storage materials) such as ammonia-borane.
