A ligand-free and room temperature protocol for the synthesis of 2,4-diarylquinolines is described. Treatment of 4-chloro-2-arylquinolines with arylmagnesium halides in the presence of a catalytic amount of nickel(II) chloride without ligands in 2-methyltetrahydrofuran (2-MeTHF) afforded the corresponding cross-coupling products in good yields.
描述了用于合成 2,4-二芳基喹啉的无配体和室温协议。在催化量的氯化镍 (II) 存在下,在 2-甲基四氢呋喃 (2-MeTHF) 中没有配体的情况下,用芳基卤化镁处理 4-氯-2-芳基喹啉,以良好的产率得到相应的交叉偶联产物。
