Application of 166330-10-5. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine)
The often applied in situ formation of neutral dinuclear rhodium precatalysts of the type [Rh(Diphosphine)(mu2-Cl)]2 with the ligands DPEPhos and DIOP has been mechanistically investigated by NMR spectroscopy. The structural characterization of reaction intermediates [Rh2(mu2-Diphosphine)(COD)2(Cl)2] and [Rh2(Diphosphine)(COD)(mu2-Cl)2] was accomplished using X-ray crystallography. So a new and unexpected intermediate was found, which casts a new light on the mechanism of this ligand exchange. In addition, equilibria could be found which can at least influence the formation of neutral dinuclear rhodium precatalysts.
