PhBF3Na

PhBF3Na is the chemical formula for sodium trifluoroborate phenyl. It is a chemical compound that falls into the category of organoboron compounds. The structure consists of a phenyl group (C6H5), a boron atom, three fluorine atoms, and a sodium cation (Na+). The trifluoroborate anion (BF3) is bonded to the phenyl group through the boron atom.

This compound has found applications in organic synthesis, particularly as a reagent in cross-coupling reactions. It can act as a source of the phenyl group, allowing for the formation of new carbon-carbon bonds. Specifically, it has been used in Suzuki-Miyaura coupling reactions, where it reacts with organic halides in the presence of a palladium catalyst to form biaryl compounds. The stability and ease of handling of PhBF3Na compared to other phenylating reagents contribute to its utility in synthetic chemistry. It is typically a solid at room temperature. Its synthesis often involves the reaction of phenylboronic acid with a source of fluoride ions and sodium ions.
