method is discussed for preparation of 1,2-diketones: Esters 1 was used as starting material, the intermediate enol 2 was obtained from sodium and trimethylsilyl chloride via acyloin condensation reaction, while bromine water was used in the further experiment as the oxidation reagent to oxidize compound 2 in the mixed solvent THF/H 2 O. Four kinds of 1,2-diketones have been synthesized in the new way
讨论了制备1,2-二酮的新方法:以酯1为起始原料,通过酰氯缩合反应从钠和三甲基甲硅烷基氯中制得中间体烯醇2,而在进一步的实验中使用溴水进行氧化。在混合溶剂THF / H 2 O中氧化化合物2的化学试剂。以这种新方式合成了四种1,2-二酮,一种是直链化合物3a,3b,另一种是环化合物3c,3d。通过IR和1 HNMR确认目标化合物。
