developed for the N‐arylation of pyrazoles using diaryliodonium salts. The transformation does not require any transition‐metal catalyst and provides the desired N‐arylpyrazoles rapidly under mild reaction condition in the presence of aqueous ammonia solution as a mild base without the use of inert atmosphere. The chemoselectivity of unsymmetric diaryliodonium salts was also explored with large number
使用二芳基碘鎓盐开发了一种新的合成方法,用于吡唑的N-芳基化。该转化不需要任何过渡金属催化剂,并且可以在温和的反应条件下,以氨水为温和碱,在不使用惰性气氛的情况下,在温和的反应条件下快速提供所需的N-芳基吡唑。还通过大量实例探讨了不对称二芳基碘鎓盐的化学选择性。
