The nickel-catalyzed cross-electrophile coupling of 1,2,3-benzotriazin-4(3H)-ones with aryl bromides to generate a diverse array of ortho-arylated benzamide derivatives has been developed. The reaction displayed good functional group tolerance with Zn as the reductant. The key to this transformation is the ring opening of benzotriazinones, which undergo a denitrogenative process to obtain various benzamide
已经开发了镍催化的 1,2,3-苯并三嗪-4(3 H )-与芳基溴的交叉亲电子偶联,以生成多种邻芳基化苯甲酰胺衍生物。该反应以 Zn 作为还原剂显示出良好的官能团耐受性。这种转化的关键是苯并三嗪酮的开环,它经过脱氮过程以获得各种苯甲酰胺衍生物(29 个例子,42-93% 产率)。证明了这种转变的可扩展性。
