preparation. Meanwhile, diaryl ketones hold potent applications in antitumor drugs, the agrochemical industry, and synthetic chemistry. Herein, we report versatile palladium-catalyzed carbonylative cross-coupling reactions of aryl thianthrenium salts with arylboronic acids. Arenes were transformed site selectively via C(sp2)–H thianthrenation, and various desired diaryl ketones were produced in good to excellent
在过去的几十年中,开发将惰性 C-H 键转化为增值分子的温和方法一直是一个有吸引力的研究课题,因为它提供了有效的制备方法。同时,二芳基酮在抗肿瘤药物、农用化学工业和合成化学中具有强大的应用前景。在此,我们报告了芳基噻蒽盐与芳基硼酸的通用钯催化羰基化交叉偶联反应。芳烃通过 C(sp 2 )–H 噻蒽化反应进行位点选择性转化,并以良好至优异的收率生产出各种所需的二芳基酮。
