Category: tetrahydropyran. 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: 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride, is researched, Molecular C27H36Cl2N2, CAS is 1228185-09-8, about 18F-Deoxyfluorination of Phenols via Ru π-Complexes. Author is Beyzavi, Hudson; Mandal, Debashis; Strebl, Martin G.; Neumann, Constanze N.; D’Amato, Erica M.; Chen, Junting; Hooker, Jacob M.; Ritter, Tobias.
The deficiency of robust and practical methods for 18F-radiofluorination is a bottleneck for positron emission tomog. (PET) tracer development. Here, we report the first transition-metal-assisted 18F-deoxyfluorination of phenols. The transformation benefits from readily available phenols as starting materials, tolerance of moisture and ambient atm., large substrate scope, and translatability to generate doses appropriate for PET imaging.
