The organic palladium complex (trans-dichlorobis(4-iodoaniline-κN)palladium(II)) was encapsulated into a porous metal–organicframework MIL-Cr (Pd complex@MIL-Cr) using ship-in-a-bottle strategy. The novel catalyst as a three dimensional nanoreactor was fully characterized using different techniques such as XRD, BET, XPS, SEM, EDX, TEM and ICP. The Pd complex@MIL-Cr is isostructural to the parent MIL-Cr
有机钯配合物(反式-二氯双(4-碘苯胺-κN)钯(II))通过瓶装策略封装在多孔的金属有机框架MIL-Cr(Pd complex @ MIL-Cr)中。使用不同的技术,如XRD,BET,XPS,SEM,EDX,TEM和ICP,对新型作为三维纳米反应器的催化剂进行了全面表征。Pd complex @ MIL-Cr与母体MIL-Cr骨架是同构的,具有约200的高表面积和孔体积。1418 m 2 g -1和0.87 cm 3 g -1, 分别。纳米反应器在芳基卤化物的催化转化中非常高效,显示出比均相Pd对应物更高的活性。出乎意料的是,在具有广泛取代基的氯代芳烃的Suzuki-Miyaura和Heck偶联反应中实现了高收率。此外,该方案可以扩展到2-溴和2,6-二溴吡啶与芳基硼酸的交叉偶联,在室温下具有优异的收率。Pd配合物@ MIL-Cr还用作制备一系列C 3的高效便捷催化剂以苯,吡啶或嘧啶单元

state NMR spectroscopy, field emission scanning electron microscopy and thermogravimetric analysis. These nitrogen rich materials act as good supports for palladiumnanoparticles (Pd NPs) and exhibit excellent catalytic activity towards Mizoroki–Heck crosscoupling between aryl bromides and alkenes. Hot filtration tests demonstrate that the presence of the triazine rings on the polymers is beneficial for

system for the high-throughput synthesis, purification, and characterization of molecules with a large variety. Based on the principle “Like dissolves like,” we combine theoretical calculations and a robotic platform to accelerate the purification of those molecules. With this platform, a material library containing 125 molecules and their optical-electronic properties was built within a timeframe of
