摘要: 在有机合成上,β-二羰基化合物的偶联是形成碳-碳键的重要方法之一.一般用化学方法 在强碱的作用下得到碳负离子,继而用弱氧化剂I2[1]、CuBr2[2]、AgNO3[3]等将碳负离子变成游 离基偶联而成.

Abstract: The indirect electrolytic oxidative coupling reaction of some activated methylene compounds was studied by using KI-NaI as the indirect electrolyte and acetone as solvent. The results showed that this oxidative system was suitable for β-dicarbonyl compounds having acidity of pK=9~13 under proper conditions to give symmetric multifunctional products in satisfactory yields.

Key words: β-dicarbonyl compound, indirect electrolytic oxidative, coupling reaction
