In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Axial Coordination of NHC Ligands on Dirhodium(II) Complexes: Generation of a New Family of Catalysts, published in 2008-06-06, which mentions a compound: 138984-26-6, mainly applied to axial coordination NHC ligand dirhodium complex generation catalyst crystallog, Recommanded Product: Dirhodium(II) tetrakis(caprolactam).
An efficient new methodol. for the arylation of aldehydes is disclosed which uses dirhodium(II) catalysts and N-heterocyclic carbene (NHC) ligands. Complexes of Rh2(OAc)4 with one and two NHCs attached on the axial positions were successfully isolated, fully characterized, and used as catalysts in the reaction. A saturated monocomplex is the most active catalyst and was particularly efficient in the arylation of alkyl aldehydes. DFT calculations support participation of complexes with one axial NHC in the reaction as the catalysts active species and indicate that hydrogen bonds involving dirhodium unit, reactants, and solvent (alc.) play an important role on the reaction mechanism.
The article 《Axial Coordination of NHC Ligands on Dirhodium(II) Complexes: Generation of a New Family of Catalysts》 also mentions many details about this compound(138984-26-6)Recommanded Product: Dirhodium(II) tetrakis(caprolactam), you can pay attention to it, because details determine success or failure
