Ligand‐free C‐arylation: A general palladium‐catalyzed C‐arylation of N‐heterocycles with aryl bromides has been performed without the presence of phosphines, the aid of CuI, or other metal additives by using pivalic acid as a cocatalyst (see scheme).
无配体的C芳基化:通过使用新戊酸作为助催化剂,在不存在膦的情况下,借助CuI或其他金属添加剂的情况下,进行了N杂环与芳基溴化物的一般钯催化C芳基化反应。 )。
