An effective protocol for iron‐catalyzed biaryl syntheses by coupling chlorostyrenes with aryl Grignard reagents requires only mild reaction conditions and tolerates various functional groups. The underlying activation of deactivated aryl chlorides proceeds through a rate‐determining coordination of the catalyst to the vinyl substituent and subsequent haptotropic migration along the conjugated π system
通过将氯代苯乙烯与芳基格氏试剂偶联来进行铁催化联芳基合成的有效方案只需要温和的反应条件,并能耐受各种官能团。失活的芳基氯化物收益通过催化剂与乙烯基取代基和随后haptotropic迁移沿着共轭π体系,C的部位的速度决定协调底层活化 Cl键裂解。
