摘要/Abstract
在无金属和温和反应条件下, 发展了新颖的三酮单水合物与活泼炔通过连续碳-碳/碳-氧断裂的加成反应, 且反应可高效地在1 min内完成. 多样的三酮单水合物均可在1,4-二氮杂二环[2.2.2]辛烷(DABCO)的促进下, 通过这种转变与活泼炔反应, 生成多种酯类化合物.

A novel addition reaction of vicinal tricarbonyl monohydrates with active alkynes proceeded via rapid consecutive C—C/C—O cleavage processes under metal-free and mild reaction conditions, and the transformation was completed within only 1 min. Diverse tricarbonyl monohydrates could react with active alkynes to produce carboxylate esters via these transformations in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO).
Key words: C—C cleavage, C—O cleavage, addition, promoter
