A high yielding, simple, and flexible copper-based system for N-arylation of fluorinated sulfoximines is reported. Best results were achieved using copper iodide in combination with DMEDA and Cs2CO3 to provide a wide range of N-arylated perfluoroalkylated sulfoximines. These conditions tolerate a great number of substituents on either aromatic cycle, including heteroaromatic rings, for the N-functionalization
据报道,用于氟化亚砜亚胺的N-芳基化的高产量,简单且灵活的铜基体系。碘化铜与DMEDA和Cs 2 CO 3组合使用可提供最佳的N-芳基化全氟烷基化亚砜基亚胺,从而获得最佳结果。这些条件容许任一芳香环上的许多取代基,包括杂芳香环,用于N-官能化。
