availability and low toxicity of the required reagents, mild reaction conditions, and functional group compatibility. Nevertheless, few conditions can be used to cross-couple alkyl boronic acids or esters with aryl halides, especially 2-pyridyl halides. Herein, we describe two novel Suzuki–Miyaura protocols that enable selective conversion of polychlorinated aromatics, with a focus on reactions to convert
在交叉偶联反应中,Suzuki-Miyaura转化因其实际优势而脱颖而出,其中包括商业上可获得的试剂和所需试剂的低毒性,温和的反应条件以及官能团的相容性。然而,几乎没有条件可用于烷基硼酸或酯与芳基卤化物,特别是2-吡啶基卤化物的交联。在这里,我们描述了两个新颖的Suzuki-Miyaura协议,它们能够选择性地转换多氯代芳烃,重点是将2,6-二氯吡啶转化为2-氯-6-烷基吡啶或2-芳基-6-烷基吡啶的反应。
