A novel method for palladium-catalyzed cyclotrimerization of alkynes in supercritical carbon dioxide (scCO2) has been developed. The results showed that in scCO2 cyclotrimerization of terminal acetylenes was carried out smoothly to regioselectively afford the corresponding benzene derivates using PdBr2 as the catalyst.
