Magnetite Pd-loaded nitrogen-rich porous organic polymer as a catalyst for suzuki-miyaura coupling reaction

Fe3O4@SiO2@DETA-POP/Pd (FSTNPd) recyclable magnetic nanocatalyst was synthesized, fully characterized, and its application in Suzuki-Miyaura coupling reaction was investigated. Initially, the nitrogen-rich diethylenetriamine-based porous organic polymer (DETA-POP) with high surface area was synthesized using diethylenetriamine (DETA) and cyanuric acid through dioxane-organic solvent interface method. Then, magnetic iron (II, III) oxide nanoparticles (Fe3O4 NPs) were synthesized and supported by SiO2 and (3-chloropropyl)trimethoxysilane (CPTMS). Thereafter, Fe3O4@SiO2@CPTMS was processed by DETA porous organic polymer. Further loading with Pd afforded the Fe3O4@SiO2@DETA-POP/Pd magnetically recoverable heterogeneous catalyst. The catalyst showed astonishing performance in mild conditions for Suzuki–Miyaura coupling reaction in water/ethanol. The collected data represent excellent catalytic activity of this catalyst, good yields of the products, simple work-up procedure, and short reaction times.
