超临界二氧化碳介质中钯催化末端炔烃双羰基化反应的研究

Palladium-Catalyzed Dicarbonylation of Terminal Alkynes in Supercritical Carbon Dioxide

在超临界二氧化碳介质中 ,钯催化末端炔烃双羰基化反应时需要加入适当量的醇作为共溶剂 ,反应才能顺利进行 。

In supercritical carbon dioxide, it is necessary to add an excess of alcohol as co-solvent to facilitate palladium-catalyzed dicarbonylation of terminal alkynes and the results of the palladium-catalyzed dicarbonylation of terminal alkynes in supercritical carbon dioxide is different from those in convention organic solvent to some extent.
