【Abstract】 A novel method for palladium-catalyzed cyclotrimerization of alkynes in supercritical carbon dioxide (scCO 2) has been developed. The results showed that in scCO 2 cyclotrimerization of terminal acetylenes was carried out smoothly to regioselectively afford the corresponding benzene derivates using PdBr 2 as the catalyst.更多还原
