Catalytic reduction of carboxylic acid to the corresponding alcohol is a challenging task of great importance for the production of a variety of value-added chemicals. Herein, a manganese-catalyzed chemoselective hydroboration of carboxylic acids has been developed with a high turnover number (>99 000) and turnover frequency (>2000 h–1) at 25 °C. This method displayed tolerance of electronically and
将羧酸催化还原成相应的醇是具有挑战性的任务,对于生产各种增值化学品而言,这一任务非常重要。在此,已开发出锰催化的羧酸的化学选择性氢硼化反应,其在25°C时具有较高的周转数(> 99 000)和周转频率(> 2000 h –1)。该方法显示了具有高化学选择性的电子和空间分化底物的耐受性。重要的是,可以有效地还原脂族长链脂肪酸,包括生物质衍生的化合物。机理研究表明,该反应是通过插入和键易位类型机制,通过活性锰氢化物物种的形成而发生的。
