The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)( cas:32305-98-9 ) is researched.Related Products of 32305-98-9.Moeller, Saskia; Kubis, Christoph; Drexler, Hans-Joachim; Alberico, Elisabetta; Heller, Detlef published the article 《Investigations into the mechanism of the in situ formation of neutral dinuclear rhodium complexes》 about this compound( cas:32305-98-9 ) in Journal of Organometallic Chemistry. Keywords: neutral dinuclear cyclooctadiene rhodium diphosphine preparation crystal mol structure. Let’s learn more about this compound (cas:32305-98-9).
The often applied in situ formation of neutral dinuclear rhodium precatalysts of the type [Rh(Diphosphine)(μ2-Cl)]2 with the ligands DPEPhos and DIOP has been mechanistically investigated by NMR spectroscopy. The structural characterization of reaction intermediates [Rh2(μ2-Diphosphine)(COD)2(Cl)2] and [Rh2(Diphosphine)(COD)(μ2-Cl)2] was accomplished using x-ray crystallog. So a new and unexpected intermediate was found, which casts a new light on the mechanism of this ligand exchange. In addition, equilibrium could be found which can at least influence the formation of neutral dinuclear rhodium precatalysts.
《Investigations into the mechanism of the in situ formation of neutral dinuclear rhodium complexes》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound((((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine))Related Products of 32305-98-9.
