The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate, is researched, Molecular C21H25BF4N2, CAS is 286014-53-7, about Copper-Catalyzed Direct Aryl Quaternization of N-Substituted Imidazoles to Form Imidazolium Salts, the main research direction is copper catalyzed quaternization imidazole aryliodonium salt; imidazolium salt preparation; triazolium salt preparation.Application of 286014-53-7.
Diaryliodonium salts are employed to directly quaternize N-substituted imidazoles by using a copper catalyst to construct aryl imidazolium salts in moderate to excellent yields [e.g., N-phenylimidazole + diphenyliodonium tetrafluoroborate in presence of Cu(OAc)2 in DMF afforded 97% 1,3-diphenylimidazolium tetrafluoroborate]. This transformation is tolerant to a broad range of functional groups and provides a straightforward, efficient, and versatile route to synthesize aryl imidazolium as well as triazolium salts, especially the unsym. version.
