Pd(II)-catalyzed C–H functionalization of nondirected arenes has been realized using an inexpensive and easily accessible type of bidentate S,O-ligand. The catalytic system shows high efficiency in the C–H olefination reaction of electron-rich and electron-poor arenes. This methodology is operationally simple, scalable, and can be used in late-stage functionalization of complex molecules. The broad
Pd(II)催化的非定向芳烃的C–H功能化已通过使用廉价且易于获得的双齿S,O-配体实现。催化体系在富电子和贫电子的芳烃的C–H烯化反应中显示出很高的效率。这种方法操作简单,可扩展,可用于复杂分子的后期功能化。该催化剂的广泛适用性已在其他转化中得到了证明,例如Pd(II)催化的C–H乙酰氧基化和烯丙基化反应。
