Abstract

Reactions of aldehydes, 1,3-indanedione and enaminones were successfully carried out using p-toluene sulfonic acid (p-TsOH) as a catalyst and high-temperature water as a solvent under microwave irradiation. This method provided several advantages such as rapid reaction times, high yields, and a simple workup procedure. In addition, a possible mechanism to account for the reaction was proposed.

摘要

在微波辐射下,以对甲苯磺酸(p-TsOH)为催化剂、高温水为溶剂,成功实现了醛、1,3-茚二酮和烯胺酮的反应。该方法具有反应时间短、产率高和后处理程序简单等优点。此外,还提出了一种可能的反应机理。
