The mechanochemical, solvent‐free, highly regioselective, rhodium‐catalyzed C−H methylation of (hetero)arenes is reported. The reaction shows excellent functional‐group compatibility and is demonstrated to work for the late‐stage C−H methylation of biologically active compounds. The method requires no external heating and benefits from considerably shorter reaction times than previous solution‐based
报道了(杂)芳烃的机械化学、无溶剂、高度区域选择性、铑催化的 C−H 甲基化。该反应表现出优异的官能团相容性,并被证明适用于生物活性化合物的后期 C−H 甲基化。该方法不需要外部加热,并且反应时间比之前基于溶液的 CH 甲基化方案要短得多。此外,机械化学方法被证明可以有效合成传统方法难以生成的有机金属配合物。
