Nickel-catalyzed cross-coupling of methoxyarenes with alkyl Grignard reagents, which involves the cleavage of the C(aryl)–OMe bond, has been developed. The use of 1,3-dicyclohexylimidazol-2-ylidene as a ligand allows the introduction of a variety of alkyl groups, including Me, Me3SiCH2, ArCH2, adamantyl, and cyclopropyl. The method can also be used for the alkylative elaboration of complex molecules
已经开发了镍催化的甲氧基芳烃与烷基格氏试剂的交叉偶联,这涉及到C(芳基)-OMe键的裂解。使用1,3-二环己基咪唑-2-亚烷基作为配体允许引入各种烷基,包括Me,Me 3 SiCH 2,ArCH 2,金刚烷基和环丙基。该方法还可用于带有C(芳基)–OMe键的复杂分子的烷基化修饰。
