研究了以超临界二氧化碳为反应介质实现改善钯催化炔烃羰基化反应绿色性的方法.研究结果表明:醇的用量、二氧化碳压力和反应温度等因素均对钯催化炔烃羰基化反应的化学选择性均有影响,即存在炔烃的羰基化反应与氧化偶合反应的竞争.

An improved method for the palladium-catalyzed carbonylation of terminal acetylenes using supercritical carbon dioxide as the reaction medium has beendeveloped. The amount of alcohol, the pressure of carbon dioxide, and the reaction temperature were found to affect the chemoselectivity of the palladium-catalyzedcarbonylation of terminal acetylenes in supercritical carbon dioxide, i.e.there is a competition between carbonylation and oxidative coupling of terminal acetylenes.

Key words: supercritical carbon dioxide, terminal acetylene, carbonylation, oxidation coupling reaction
