A conceptual method for the preparation of 1,2-diketones is reported. The selective C–C bond cleavage of 1,3-diketones affords the 1,2-diketones in high yields under mild reaction conditions in air by the use of FeCl3 as the catalyst and tert-butyl nitrite (TBN) as the oxidant without the use of solvent. The possible reaction mechanism is discussed. This protocol provides an expeditious route to the
报告了一种制备1,2-二酮的概念方法。通过使用FeCl 3作为催化剂和使用亚硝酸叔丁酯(TBN)作为氧化剂,在温和的反应条件下,在空气中温和的反应条件下,1,3-二酮的选择性C-C键裂解可高产率地提供1,2-二酮使用溶剂。讨论了可能的反应机理。该协议为获得有用的1,2-二酮提供了一条快捷途径。
