organosulfonate-based metal–organic framework (MOF) with a defective primitive–cubic (pcu) topology was successfully synthesized. The unusual missing linkers, along with the highest permanent porosity (∼43%) in sulfonate-MOFs, offer a versatile platform for the incorporation of alkynophilic Ag(I) sites. The cyclic carboxylation of alkyne molecules (e.g., propargyl alcohol and propargyl amine) into α-alkylidene
成功合成了具有缺陷的原始-立方(pcu)拓扑结构的非互穿有机磺酸盐基金属-有机骨架(MOF)。磺酸盐-MOF中不常见的缺失连接基以及最高的永久孔隙度(约43%)为结合嗜碱性的Ag(I)位点提供了一个多功能的平台。炔烃分子(例如,炔丙醇和炔丙基胺)的环状羧化反应通过在Ag 2的大气压下使用Ag(I)嵌入的磺酸盐-MOF成功地催化了α-亚烷基环状碳酸酯和恶唑烷酮。在使用CO 2作为C1原料的所有三个催化反应中,高度坚固的磺酸盐基MOF催化剂显示出至少三循环的可重复使用性。
