    in good to high yields. For electron-poor aryl bromides, the addition of AgBF4 is the crucial point to accelerate the coupling reaction to give the arylated products in moderate yields. Pyridine also reacts with electron-rich aryl bromides catalyzed by Cy3PAuCl to give a mixture of arylated regioisomers in moderate yield. However, in order to realize the direct C–H arylation of pyridine with electron-poor
    描述了一种有效的方法,用于将电子贫乏的芳族化合物(例如吡嗪和吡啶)与芳基Bomides直接进行C-H芳基化。在催化量的Cy 3 PAuCl存在下,并使用t -BuOK作为碱,吡嗪在100°C下与芳基溴直接进行CH H芳基化,芳基化产物的收率取决于芳基的性质溴化物。在使用富含电子的芳基溴化物的情况下,可以高产率或高产率获得芳基化的吡嗪。对于贫电子芳基溴化物,添加AgBF 4是加快偶联反应以适度收率得到芳基化产物的关键点。吡啶还与Cy 3催化的富电子芳基溴反应PAuCl以中等产率得到芳基化的区域异构体的混合物。然而,为了实现吡啶与贫电子芳基溴的直接C–H芳基化,需要添加银盐作为添加剂,并且需要较温和的反应温度(60°C)。
