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 18F-Deoxyfluorination of Phenols via Ru π-Complexes, published in 2017-09-27, which mentions a compound: 1228185-09-8, Name is 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride, Molecular C27H36Cl2N2, Computed Properties of C27H36Cl2N2.
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.
In addition to the literature in the link below, there is a lot of literature about this compound(2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride)Computed Properties of C27H36Cl2N2, illustrating the importance and wide applicability of this compound(1228185-09-8).
