In this thesis, investigations focused on heteropoly acids-catalyzed C-C and C-N bond formation reactions and the synthesis of xanthenediones and acridinediones under thermal conditions are described.1.12-Phosphotungstic acid has been used as an efficient,eco-friendly,and air- and moisture-stable catalyst to promote the direct dehydrative substitution of the hydroxy group of benzylic and allylic alcohols with variousβ-dicarbonyl compounds.
本篇论文主要描述了杂多酸催化下的C-C和C-N键的生成,以及无溶剂直接加热下合成十氢氧杂蒽二酮和9-芳基十氢吖啶二酮。主要内容如下:1。在磷钨酸催化下,1,3-二羰基化合物与醇能够顺利偶合,脱除一分子的水,生成烷基化的1,3-二羰基化合物。反应在甲苯中进行时,二芳基甲醇能与各类1,3-二羰基化合物反应,成率很高;但对于1-苯乙醇,只能得到很低的产率。
