photoreductant, a Miyaura borylation, has been achieved. This simple, scalable, and novel borylation method that makes use of the hexachlorocerate(III) anion ([CeIIICl6]3−, derived from CeCl3) has a broad substrate scope and functional‐group tolerance and can be conducted at room temperature. Combined with Suzuki–Miyaura cross‐coupling, the method is applicable to the synthesis of various biaryl products, including
稀土金属光还原剂Miyaura硼酸盐化反应实现了第一个光诱导的碳(sp 2)-杂原子键形成反应。这种简单,可扩展且新颖的硼酸化方法利用六氯cerate(III)阴离子([Ce III Cl 6 ] 3−,源自CeCl 3),具有广泛的底物范围和官能团耐受性,可以在室温下进行温度。结合Suzuki-Miyaura交叉偶联,该方法适用于各种联芳基产物的合成,包括通过使用芳基氯化物底物。
