Assembly of 5-nitro-1,2,3-benzenetricarboxylic acid (H3nbta) with CuII in the presence of 1,3-bis(1,2,4-triazol-1-yl)propane (1,3-btp) leads to a new metalâorganic framework, [Cu(Hnbta)(1,3-btp)]·2H2O (A1), which is shown to be an efficient and recyclable heterogeneous catalyst for enamination of β-ketoesters with excellent product yields and selectivity.
在1,3-双(1,2,4-三唑-1-基)丙烷(1,3-btp)的存在下,5-硝基-1,2,3-苯三甲酸(H3nbta)与CuII组装形成了一种新的金属有机骨架[Cu(Hnbta)(1,3-btp)]·2H2O(A1),该框架被证明是一种高效且可循环的非均相催化剂,用于β-酮酯的烯胺化反应,具有优异的产物收率和选择性。
