In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Ligand-Controlled Regiodivergent Enantioselective Rhodium-Catalyzed Alkene Hydroboration, published in 2019, which mentions a compound: 36620-11-8, mainly applied to ligand controlled regiodivergent enantioselective rhodium catalyzed alkene hydroboration; chiral alc enantioselective preparation; boronate chiral preparation oxidation; asymmetric catalysis; homogeneous catalysis; hydroboration; regiodivergent reactions; rhodium, Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate.
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.
Although many compounds look similar to this compound(36620-11-8)Name: Bis(norbornadiene)rhodium (I) tetrafluoroborate, numerous studies have shown that this compound(SMILES:[F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10), has unique advantages.
