Aerobic oxidation reactions have been the focus of considerable attention, but their use in mainstream organic chemistry has been constrained by limitations in their synthetic scope and by practical factors, such as the use of pure O(2) as the oxidant or complex catalyst synthesis. Here, we report a new (bpy)Cu(I)/TEMPO catalyst system that enables efficient and selective aerobic oxidation of a broad
好氧氧化反应一直是备受关注的焦点,但它们在主流有机化学中的使用受到其合成范围和实际因素的限制,例如使用纯 O(2) 作为氧化剂或复合催化剂合成。在这里,我们报告了一种新的 (bpy)Cu(I)/TEMPO 催化剂系统,该系统能够使用现成的试剂将广泛的伯醇(包括烯丙基、苄基和脂肪族衍生物)高效和选择性地有氧氧化成相应的醛,在室温下,以环境空气为氧化剂。该催化剂体系与多种官能团相容,对 1° 醇的高选择性使缺乏保护基团的二醇能够选择性氧化。
