Formula: C14H8BF4Rh. 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 A Gallium-based Chiral Solvating Agent Enables the Use of 1H NMR Spectroscopy to Differentiate Chiral Alcohols. Author is Jang, Sumin; Kim, Hyunwoo.
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.
