We report the magnesiation of aryl fluorides cata-lyzed by a Al-Rh heterobimetallic complex. We show that the complex is highly reactive to cleave the C-F bonds across the polarized Al-Rh bond under mild conditions. The reaction allows the use of an easy-to-handle magnesium powder to gener-ate a range of arylmagnesium reagents from aryl fluorides, which are conventionally inert to such metalation compared with other aryl halides.

铑铝配合物催化芳基氟化物的镁化

我们报告了由 Al-Rh 异质双金属配合物催化的芳基氟化物的镁化。我们表明，在温和条件下，该复合物具有高度反应性，可以裂解极化 Al-Rh 键上的 CF 键。该反应允许使用易于处理的镁粉从芳基氟化物生成一系列芳基镁试剂，与其他芳基卤化物相比，芳基氟化物通常对此类金属化呈惰性。
