Abstract

A simple and efficient method for the construction of symmetrical and unsymmetrical diaryl sulfones has been developed. Herein, Cu(OAc)₂-catalyzed oxidative cross-coupling of aryl sulfonyl hydrazides and aryl hydrazine easily afforded the diaryl sulfones in the presence of K₂CO₃ base and DMSO medium. Notably, a variety of diaryl sulfone derivatives have been synthesized in moderate to good yields.

铜催化磺酰肼与芳基肼交叉偶联合成二芳基砜

提出了一种简单有效的对称和不对称二芳基砜的合成方法。在K2CO3碱和DMSO介质存在下，Cu(OAc)2催化芳基磺酰肼和芳基肼的氧化交偶联反应容易生成芳基砜。值得注意的是，各种二芳基砜衍生物已合成在中等到良好的产量。
