alkylidene fluorenes and their heteroarene derivatives has been developed successfully by means of a Pd(II)-catalyzed direct C–H/C–H coupling of o-alkenyl biaryls. Use of the Pd(OAc)2 catalyst under aerobic oxidation conditions gives rise to the corresponding alkylidene fluorenes having various functional groups and diversely fused polycyclic systems. The resulting products can serve as versatile synthetic
通过 Pd(II) 催化的邻烯基联芳基的直接 C-H/C-H 偶联,成功开发了一种用于构建亚烷基芴及其杂芳烃衍生物的多功能合成方法。在有氧氧化条件下使用 Pd(OAc) 2催化剂会产生相应的具有各种官能团和不同稠合多环体系的亚烷基芴。所得产物可用作构建结构多样的多环芳烃和杂芳烃的多功能合成构件。
