SDS of cas: 36620-11-8. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Ligand-Controlled Regiodivergent Enantioselective Rhodium-Catalyzed Alkene Hydroboration. Author is Bochat, Andrew J.; Shoba, Veronika M.; Takacs, James M..
Regiocontrol in the Rh-catalyzed boration of vinyl arenes is typically dominated by the presence of the conjugated aryl substituent. However, small differences in TADDOL-derived chiral monophosphite ligands can override this effect and direct Rh-catalyzed hydroboration of β-aryl and β-heteroaryl methylidenes by pinacolborane to selectively produce either chiral primary or tertiary borated products. The regiodivergent behavior is coupled with enantiodivergent addition of the borane. The nature of the TADDOL backbone substituents and that of the phosphite moiety function synergistically to direct the sense and extent of regioselectivity and enantioinduction. Twenty substrates undergo each reaction mode with regioselectivity values reaching >20:1 and enantiomer ratios reaching up to 98:2. A variety of subsequent transformations illustrate the potential utility of each product.
After consulting a lot of data, we found that this compound(36620-11-8)SDS of cas: 36620-11-8 can be used in many types of reactions. And in most cases, this compound has more advantages.
