We report herein a transition-metal-free coupling reaction of arylboronic acids with benzyl halides and mesylates for the construction of C(sp2)C(sp3) bonds. A unique feature of this coupling reaction is the formation regioisomers in some cases. Mechanistic studies suggest that this reaction may proceed via an unprecedented Friedel–Crafts-type reaction pathway under base conditions with the assistance
我们在这里报告芳基硼酸与苄基卤化物和甲磺酸盐的C(sp 2)C(sp 3)键的建设无过渡金属的偶联反应。在某些情况下,这种偶联反应的一个独特特征是区域异构体。机理研究表明,在碱性条件下,借助硼酸部分,该反应可能会通过空前的Friedel-Crafts型反应路径进行。
