Chloro(1,5-cyclooctadiene)rhodium(I) dimer
CAS 12092-47-6
[Rh(COD)Cl]₂ is the universal Rh(I) building block — the dimer from which asymmetric hydrogenation, hydroboration and C–H functionalization catalysts are assembled with chiral and achiral ligands alike.

Where [Rh(COD)Cl]₂ is used
Asymmetric catalysis
Charged with BINAP, DuPhos or Josiphos-type ligands it generates the cationic Rh(I) catalysts behind industrial asymmetric hydrogenations, including amino-acid and pharma intermediate processes.
Arylboronic acid addition and C–H chemistry
The standard precursor for Rh-catalyzed 1,4-additions of boronic acids and for directed C–H functionalization methodology across medicinal chemistry.
Storage and shipping

Frequently asked questions
How is pricing structured?
Quotes reference the day's metal fixing on assayed contained metal plus a stated conversion charge, and can be locked at order confirmation for recurring volumes.
What documentation is included?
Every lot ships with a certificate of analysis stating assayed metal content, plus an English SDS. ICP trace-metal panels are available on request.
Do you take back spent material?
Yes — spent catalyst, residues and off-spec lots are assayed on receipt and the recovered metal credited against your next order, closing the loop on your metal inventory.
