are an important class of compounds in many fields. Here, we report an efficient light-induced arylation (alkylation) for the synthesis of diarylmethanes, bis(diarylmethyl)benzenes, arylalkylmethanes, and triarylmethanes from readily accessible N-sulfonylhydrazones and aryl/alkylboronic acids with the aid of Cs2CO3. In the presence of light, the synthesis of diarylmethanes was also achieved from aldehydes
二芳基甲烷和三芳基甲烷是许多领域中一类重要的化合物。在这里,我们报道了一种有效的光诱导芳基化(烷基化),用于借助 Cs 2 CO 3从容易获得的N-磺酰腙和芳基/烷基硼酸合成二芳基甲烷、双(二芳基甲基)苯、芳基烷基甲烷和三芳基甲烷。在光存在下,二芳基甲烷的合成也可以通过三组分方法以一锅法从醛合成,收率良好。此外,我们还通过合成有机硼化合物和2°-醇证明了其合成实用性。
