In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A Gallium-based Chiral Solvating Agent Enables the Use of 1H NMR Spectroscopy to Differentiate Chiral Alcohols, published in 2019-09-27, which mentions a compound: 36620-11-8, Name is Bis(norbornadiene)rhodium (I) tetrafluoroborate, Molecular C14H8BF4Rh, Category: quinuclidine.
In situ, direct 1H NMR chiral anal. by using chiral solvating agents is a convenient and efficient anal. technique. Here we developed a Ga-based chiral anionic metal complex for 1H NMR chiral anal. of alcs. Utilizing the optimal pKa value, the Ga complex was able to differentiate 1H NMR signals of each (R)- and (S)-enantiomer of alcs., measured at room temperature This direct 1H NMR chiral anal. of alcs. was used to rapidly determine enantiomeric excess and conversion in a kinetic resolution and an asym. synthesis.
Although many compounds look similar to this compound(36620-11-8)Category: quinuclidine, 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.
