A urea-containing metal-organic framework (MOF) was synthesized from a V-shaped dicarboxylate ligand and Cu(II) ions. As the undesirable self-aggregation of the urea moiety has been prohibited in the framework, this MOF can act as a heterogeneous hydrogen bond-donating (HBD) catalyst, which accelerates the cyanosilylation reaction of aldehydes, the Henry reaction of aldehydes, and the methanolysis
由V形二羧酸配体和Cu(II)离子合成了含尿素的金属有机骨架(MOF)。由于在框架中禁止了脲部分的不希望的自聚集,因此该MOF可以充当非均相给氢键(HBD)催化剂,从而加速醛的氰基硅烷化反应,醛的亨利反应和甲醇分解。环氧化物的反应。与同质的尿素对应物和类似的MOF结构相比,它还显示出显着增强的催化活性。
