Bis(1,5-cyclooctadiene)rhodium(I) hexafluoroantimonate
Bis(1,5-cyclooctadiene)rhodium(I) hexafluoroantimonate (CAS 130296-28-5; C16H24F6RhSb; molar mass 555.02 g/mol) is a cationic rhodium(I) complex, [Rh(COD)2]SbF6, supplied as a solid of 97% assay. The two labile 1,5-cyclooctadiene ligands and weakly coordinating hexafluoroantimonate counter-ion make it a convenient cationic rhodium precursor for homogeneous catalysis, including asymmetric hydrogenation, C-C bond-forming reactions and ligand-exchange chemistry. Tech Serve Solutions supplies it as a research-grade reagent to laboratories worldwide.

Cationic rhodium catalyst precursor
Serves as a source of the [Rh(COD)2]+ cation, in which the two 1,5-cyclooctadiene ligands are readily displaced and the hexafluoroantimonate ion is weakly coordinating. This makes it a versatile precatalyst for homogeneous rhodium-catalysed transformations.
Asymmetric metallocomplex catalysis
Used in the preparation and study of rhodium complexes bearing chiral phosphorus mono- and bidentate ligands, such as diamidophosphite ligands, for asymmetric catalysis. Combination with a chiral ligand generates the active enantioselective catalyst in situ.
C-C bond-forming hydrogenation
Applied as a catalyst in C-C bond-forming hydrogenation chemistry, where rhodium mediates coupling under a hydrogen atmosphere or transfer-hydrogenation conditions to build new carbon-carbon bonds.
[3+2] cycloaddition catalysis
Employed as a rhodium catalyst for [3+2] cycloaddition reactions used in the construction of carbocyclic and heterocyclic ring systems in synthetic chemistry.
Research and method development
Used in academic and industrial laboratories for the development of new homogeneous catalytic methods, ligand screening and mechanistic studies in organometallic chemistry.
