metal–organic framework (MOF) 1, having dual functionalities, namely, Lewis acid and basic sites, has been explored as a heterogeneous catalyst. This MOF, because of its large void volume (10298 Å3, 67.6%), large surface area (1480 m2/g), and high thermal stability, encouraged us to see its applicability in two catalytic reactions, namely, oxidative C–O coupling (cross-dehydrogentaive coupling reaction) involving
具有双功能性,即路易斯酸和碱性位点的健壮的基于铜(II)的桨轮金属-有机骨架(MOF)1已被研究用作多相催化剂。这MOF因为它的大的空隙体积(10298埃,3,67.6%),比表面积大(1480米2/ g)和高的热稳定性,鼓励我们看到它在两种催化反应中的适用性,即,在无溶剂和环境条件下,涉及直接C–H活化的氧化C–O偶联反应(交叉脱氢gentaive偶联反应)和Friedländer反应。这项研究证明了MOF在偶联反应中的绿色方面,因为其简化的回收,更短的反应时间,最少的浪费以及C–H键的平滑活化,这在合成化学中是非常具有挑战性的。
