摘要
以多聚磷酸 (PPA)为催化剂和反应溶剂 ,2 -丁烯酸为酰化剂 ,对二苯并 -2 4-冠 -8进行酰化 ,成功地合成了双茚满酮型二苯并 -2 4-冠 -8。产物由 IR、MS和元素分析鉴定了其结构。
Diindanone dibenzo-24-crown-8 is synthesized under the condition of polyphosphoric acid (PPA) as catalyst and solvent,2-butenoic acid as acylating agent and dibenzo -24-crown-8 is acylated. The products are characterized by IR, MS and elements analysis.
