A new method has been developed for the nickel-catalyzed homocoupling of methoxyarenes via C–O bond cleavage using a diboron reagent. The use of 1,3-dicyclohexylimidazol-2-ylidene as a ligand was found to be critical to the success of the reaction. This new method allows the synthesis of a wide range of biaryl compounds.
已经开发出一种新方法,可通过使用二硼试剂通过C–O键断裂来对甲氧基芳烃进行镍催化的均偶联反应。已发现使用1,3-二环己基咪唑-2-亚基作为配体对于反应的成功至关重要。这种新方法可以合成多种联芳基化合物。
