Application In Synthesis of 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate. 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: 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate, is researched, Molecular C21H25BF4N2, CAS is 286014-53-7, about Cu(I)-NHC-Catalyzed Silylation of Allenes: Diastereoselective Three-Component Coupling with Aldehydes. Author is Rae, James; Hu, Ya Chu; Procter, David J..
Copper-catalyzed silylation of aryl allenes using a silylborane reagent affords vinyl silane building blocks with high efficiency. The use of a seven-membered NHC ligand proved crucial for high regioselectivity. The catalytically generated allylcoppper intermediates were intercepted by aldehydes in a diastereoselective three-component coupling to furnish homoallylic alcs.
This literature about this compound(286014-53-7)Application In Synthesis of 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroboratehas given us a lot of inspiration, and I hope that the research on this compound(1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate) can be further advanced. Maybe we can get more compounds in a similar way.
