The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate(SMILESS: [F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10,cas:36620-11-8) is researched.Computed Properties of C18H13BCl3F4N3O. The article 《P-Chirogenic Diphosphazanes with Axially Chiral Substituents and Their Use in Rh-Catalyzed Asymmetric Hydrogenation》 in relation to this compound, is published in Journal of Organic Chemistry. Let’s take a look at the latest research on this compound (cas:36620-11-8).
A convenient synthesis of enantiopure P-chirogenic diphosphazanes incorporating bulky bisphenol and 1,1′-bi-2-naphthol-derived substituents via the functionalization of a readily accessible enantiopure lithium phosphinoamide with chlorophosphoridites was developed. Since the product requires no subsequent deprotection, the protocol provides an easy, convenient synthesis of P-chirogenic ligands on the gram scale. The ligands were applied in the Rh-catalyzed asym. hydrogenation of benchmark substrates furnishing enantiomeric excess values up to 96%.
