site‐selective C3‐arylation of N‐methyl‐2‐oxindole with arylboronic acids at room temperature in aqueous media to yield a series of 3‐aryl‐N‐methyl‐2‐oxindoles. This catalytic reaction progressed well with a low catalyst loading (0.01 mol %) under open‐flask conditions. Notably, a column‐chromatography‐free method for the quantitative preparation of C3‐arylated N‐methyl‐2‐oxindoles is reported. The catalyst
两种新型Pd II ONO钳形络合物可有效地用作均相催化剂,用于在室温下在水性介质中将N-甲基-2-氧吲哚与芳基硼酸进行定点C3芳基化,生成一系列3-芳基-N-甲基-2-氧吲哚 在开瓶条件下,该催化剂的催化反应进展顺利,催化剂负载量低(0.01 mol%)。值得注意的是,据报道,采用了无柱色谱法定量制备C3芳基化的N-甲基-2-氧吲哚。该催化剂与多种底物表现出良好的相容性,并在多达五个连续运行中具有可回收性,而没有明显的收率损失。
