A catalytic method was developed to synthesize primary arylamines from the corresponding aryl bromides and iodides under mild conditions (yields = 80–99%). Crystalline 2,2,2-trifluoroacetamide was used as ammonia surrogate and CuI/N,N′-dimethyl ethylenediamine was used as catalyst to achieve the C–N cross-coupling.
开发了一种催化方法,可以在温和的条件下从相应的芳基溴化物和碘化物合成伯芳基胺(收率= 80–99%)。结晶2,2,2-三氟乙酰胺被用作氨替代物,而CuI / N,N'-二甲基乙二胺被用作催化剂以实现C-N交叉偶联。
