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.Synthetic Route of C8H9ClN2O. The article 《Ligand-Controlled Regiodivergent Enantioselective Rhodium-Catalyzed Alkene Hydroboration》 in relation to this compound, is published in Angewandte Chemie, International Edition. Let’s take a look at the latest research on this compound (cas:36620-11-8).
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)Application In Synthesis of Bis(norbornadiene)rhodium (I) tetrafluoroborate can be used in many types of reactions. And in most cases, this compound has more advantages.
