A heterogeneous ZIF-90-based catalyst functionalized with COOH and with a porous structure was facilely prepared for efficient CO adsorption and activation to undergo reductive -formylation with a wide range of amines (15 examples) to furnish -formamides (78-94% yields). The -COO species generated by an interaction with amine acts as a key species for activating hydrosilane to capture CO, and remarkably facilitates a cascade C-N coupling and hydrogenation process. Our findings show a facile strategy for the rational construction of robust active sites for reductive CO valorization.
一种具有羧酸官能团和多孔结构的非均相 ZIF-90 基催化剂被简便地制备出来，用于高效吸附和活化 CO，以广泛的胺（15 个实例）进行还原甲酰化反应，生成甲酰胺（78-94%收率）。与胺相互作用生成的 -COO 物种作为活化硅烷以捕获 CO 的关键物种，显著促进级联 C-N 偶联和氢化过程。我们的研究结果表明了一种用于合理构建用于 CO 还原增值的强活性位点的简便策略。
