A new metal–organic framework (MOF) composed of urea-containing tetracarboxylate struts was synthesized, and its hydrogen bonding capabilities were evaluated. The catalytic performance of this heterogeneous framework is enhanced through preactivation with silyl Lewis acids, leading to Friedel–Crafts reaction rates greater than those of common homogeneous hydrogen bond donors.
合成了一种新的金属有机骨架(MOF),该骨架由含脲的四羧酸盐撑杆组成,并对其氢键结合能力进行了评估。通过使用甲硅烷基路易斯酸进行预活化,可增强这种非均相骨架的催化性能,从而使Friedel-Crafts反应速率高于常见的均相氢键供体。
