The development of a cross‐coupling reaction protocol between aryl ethers and Grignard reagents catalyzed by carbodicarbene (CDC) nickel complexes to afford biaryl compounds through C–O cleavage is reported. Aromatic substrates featuring a broad range of electron neutral, donating, or withdrawing groups are introduced at the desired position. The method has proven effective over a wide range of naphthyl
据报道,碳二碳烯(CDC)镍配合物催化芳基醚与格氏试剂之间的交叉偶联反应方案的开发,可通过C-O裂解提供联芳基化合物。在所需位置处引入具有广泛电子中性基团,给定基团或吸收基团的芳香族底物。已证明该方法对各种萘甲基醚,茴香醚和格氏试剂均有效。通过执行多个裂解反应,克级合成和二甲氧基酯二醇衍生物的芳基化,可以验证方案的鲁棒性。
