摘要:在Friedel-Crafts酰基化反应条件下,以取代邻位二元羧酸或羧酸的衍生物合成β-环戊二酮类化合物,对反应原料及其比例、反应时间以及溶剂等影响因素作了讨论。经研究表明,丙酰氯在无水三氯化铝作用下能发生三聚,其结构已由XRD、IR、1H-NMR和MS表征,并提出了形成机理。
A convenient synthesis of βcyclopentanedione via by FriedelCrafts acylation was studied and the factors which affect the product and yield were discussed. It was also shown that the byproduct, which was identified by XRD, 1HNMR, IR and MS, was the trimer of propionyl chloride and its mechanism of formation was suggested.
