β-二酮化合物的合成

Synthesis of β-diketone Compounds

β-二酮化合物是一类能发生分子内烯醇式-酮式异构化转变的有机合成中间体,其独特的结构赋予了该化合物许多特有的光化学和配位化学性质。笔者提供了一种β-二酮化合物合成的新方法,即利用氢化钠作为碱,1,4-二氧六环作为溶剂,然后加入酯和芳基酮加热回流15 h后合成了β-二酮,且收率较高。

β-Diketone compounds is a kind of organic synthetic intermediate which can occur keto-enol tautomerism. Its u- nique structure gives the compounds many unique photochemical and coordination chemistry properties. The paper provides a new synthesis method of β-Diketone compounds. Taking sodium hydride as alkali, 1,4-dioxane as solvent, β-Diketone is syn- thesized by adding ester and aryl ketone and heating reflux for 15 hours. It has higher yield
