We have developed a nickel-catalyzed cross coupling of benzylic ammonium triflates with aryl boronic acids to afford diarylmethanes and diarylethanes. This reaction proceeds under mild reaction conditions and with exceptional functional group tolerance. Further, it transforms branched benzylic ammonium salts to diarylethanes with excellent chirality transfer, offering a new strategy for the synthesis
我们开发了一种镍催化的苄基三氟甲磺酸铵与芳基硼酸的交叉偶联,以提供二芳基甲烷和二芳基乙烷。该反应在温和的反应条件下进行,具有出色的官能团耐受性。此外,它以优异的手性转移将支化的苄基铵盐转化为二芳基乙烷,为从容易获得的手性苄基胺合成高度对映体富集的二芳基乙烷提供了一种新策略。
