In an article, published in an article, once mentioned the application of 250285-32-6, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride,molecular formula is C27H37ClN2, is a conventional compound. this article was the specific content is as follows.category: chiral-catalyst
Selective reactions between nucleophilic N,N?-diaryl-heterocyclic carbenes (NHCs) and electrophilic fluorinated alkenes afford NHC fluoroalkenes in high yields. These stable compounds undergo efficient and selective fluoride abstraction with Lewis acids to give polyfluoroalkenyl imidazolium salts. These salts react at Cbeta with pyrrolidine to give ammonium fluoride-substituted salts, which give rise to conjugated imidazolium-enamine salts through loss of HF. Alternatively, reaction with 4-(dimethylamino)-pyridine provides a Calpha-pyridinium-substituted NHC fluoroalkene. These compounds were studied using multinuclear NMR spectroscopy, mass spectrometry, and X-ray crystallography. Insight into their electronic structure and reactivity was gained through the use of DFT calculations. The unusual suspects: N,N?-Diaryl-heterocyclic carbenes react with fluorinated alkenes to afford N-heterocyclic fluoroalkenes in high yields. Efficient and selective fluoride abstraction with Lewis acids affords the first examples of polyfluoralkenyl imidazolium salts. These salts react with pyrrolidine and DMAP through different pathways to provide unique compounds.
