Chemical Properties

orange crystals

Uses

It is a widely used precursor to homogeneous catalysts. This is a chiral catalyst capable of asymmetrically hydrogenating certain prochiral alkenes. Chloro(1,5-cyclooctadiene)rhodium(I) dimer is also used in the synthesis of other metal ligands for use in catalysis.

Uses

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.

General Description

This product has been enhanced for catalytic efficiency.
