Joubert, Nicolas published the artcileMild, base-free copper-catalyzed N-arylations of heterocycles using potassium aryltrifluoroborates in water under air, SDS of cas: 14284-06-1, the publication is Tetrahedron Letters (2010), 51(22), 2994-2997, database is CAplus.
An economic, mild and efficient copper-catalyzed methodol. for the N-arylation of heterocycles was optimized using potassium aryltrifluoroborates in water. E.g., a pre-formed copper(II) Et acetoacetate complex catalyzed the N-arylation of imidazole by PhBF3K to give 26% 1-phenylimidazole.
Tetrahedron Letters published new progress about 14284-06-1. 14284-06-1 belongs to copper-catalyst, auxiliary class Copper, name is Copper(II) ethylacetoacetate, and the molecular formula is 0, SDS of cas: 14284-06-1.
