The copper particles, supported on Al2O3 were for the first time used as heterogeneous, highly active, easily available, and recyclable copper catalyst of direct carboxylation of various terminal alkynes with CO2 (2 bar) in the presence of cesium carbonate, allowing for the synthesis of alkyl 2-alkynoates. The catalyst contains large-scale CuNPs covered by oxide layer and less prone to erosion, resulting
负载在 Al2O3 上的铜颗粒首次用作非均相、高活性、易于获得和可回收的铜催化剂,在碳酸铯存在下,各种末端炔烃与 CO2(2 巴)直接羧化,允许合成2-炔酸烷基酯。该催化剂含有被氧化层覆盖的大规模 CuNPs,不易被侵蚀,因此其高选择性和效率对于这种尺寸的颗粒来说是不寻常的。
