A copper-catalyzed efficient and practical method has been developed for the synthesis of 1,2-diketones and α-keto esters. TEMPO was used as a radical initiator and scavenger, oxidizing the cleavage of α-methylene of 1,3-diketones and β-keto esters to form 1,2-diketones and α-keto esters. This method provided a general way for the formation of 1,2-dicarbonyl compounds.
已经开发出铜催化的有效且实用的方法来合成1,2-二酮和α-酮酯。TEMPO用作自由基引发剂和清除剂,氧化1,3-二酮和β-酮酯的α-亚甲基的裂解,形成1,2-二酮和α-酮酯。该方法提供了形成1,2-二羰基化合物的一般方法。
