چکیده مقاله:

In this study, a magnetic zirconium-metal organic framework (Zr-MOF, UiO-۶۶-NH۲) was solvothermally synthesized. At first, Fe۳O۴@SiO۲ nanoparticles were modified with acrylic acid and then UiO-۶۶-NH۲ was grown on them. In order to immobilize of palladium, the Zr- MOF was functionalized by ۲, ۴, ۶-trichloro-۱, ۳, ۵-triazine and ۵-phenyl tetrazole. The properties of the Fe۳O۴@modified UiO-۶۶@Pd were investigated by various techniques such as FT-IR, FESEM and EDX. The FESEM images showed particles size was around ۱۳۵ nm. After that, the catalyst tested for a coupling reaction: cyanation of aryl halides and desired products were synthesized in excellent yields. It is worth to note, mild reaction condition and shorter reaction time are the advantages of using this prepared catalyst.
