The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate( cas:286014-53-7 ) is researched.Recommanded Product: 286014-53-7.Gibard, Clementine; Ibrahim, Houssein; Gautier, Arnaud; Cisnetti, Federico published the article 《Simplified Preparation of Copper(I) NHCs Using Aqueous Ammonia》 about this compound( cas:286014-53-7 ) in Organometallics. Keywords: copper imidazolylidene imidazolinylidene preparation water ethanol aqueous ammonia; imidazolium imidazolinium reaction copper halide water ethanol aqueous ammonia. Let’s learn more about this compound (cas:286014-53-7).
The use of aqueous NH3 as a coordinating and basic reagent for the metalation of imidazol(in)ium salts derived from (S)IPr (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene, SIPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) and (S)IMes (IMes = 1,3-dimesitylimidazol-2-ylidene; SIMes = 1,3-dimesitylimidazolin-2-ylidene) with simple inorganic Cu precursors is reported. The synthesis of Cu N-heterocyclic carbene complexes was performed using aqueous/alc. media in mild conditions (room temperature to 60°) with short reaction times. Heteroleptic bromide and iodide complexes could be prepared efficiently for (S)IPr, while chloride complexes were easily accessible for SIMes and (S)IPr. NH3 also allowed the efficient synthesis of homoleptic [Cu(NHC)2](Y) (NHC = (S)IMes; Y = PF6, BF4) species by a variant procedure in EtOH.
