Pd-catalyzed cross-coupling reaction between halobenzenes and ferrocene-1,1′-diboronic acid is reported. Condensation proceeds smoothly to give 1,1′-diphenyl- and 1,1′-bis(halophenyl)-substituted ferrocenes bearing fluoro, chloro and bromo substituents in good yields. An effective synthesis of the intermediate ferrocene-1,1′-diboronic acid is described.
据报道,钯催化卤代苯与二茂铁-1,1'-二硼酸之间的交叉偶联反应。缩合顺利进行,以高收率得到带有氟,氯和溴取代基的1,1'-二苯基-和1,1'-双(卤代苯基)取代的二茂铁。描述了中间体二茂铁-1,1'-二硼酸的有效合成。
