Microwave irradiation dramatically increases the isolated yield of an alkyne cyclotrimerization step when compared to conventional heating methods. The flexibility of being able to perform a reaction in either an open or sealed vessel format provides the ability to add all reagents at the start of the reaction to take advantage of a high temperature/high pressure environment or add reagents during the reaction, reducing byproduct formation.
与传统加热方法相比,微波辐射大大增加了alkyne cyclotrimerization分离产量。在敞口和密封的条件下,均可进行反应。在反应开始前,可添加所有试剂反应试剂,在高温高压环境或添加试剂反应时,减少副产物的形成。
