Post-synthetic modification of dual-porous UMCM-1-NH2 with palladacycle complex as an effective heterogeneous catalyst in Suzuki and Heck coupling reactions

Abstract

Herein, the synthesis of a novel functionalized metal-organic-framework (MOF) UMCM-1-NH2-furfural/Pd Nano composite [UMCM-1-NH2-F2C-Pd Nano composite] is reported using the post-synthetic modification of UMCM-1-NH2. The targeted complex was prepared while chemically attaching the furfural – using Schiff base reaction followed by complexation with Pd ions. Afterward, the synthesized solid was applied as a very effective multifunctional catalyst in Suzuki and Heck coupling reactions. This technique which was facile, clean, and economically justified used only 0.01 g of the catalyst during the reaction. The easy setup, nontoxic solvent, enhanced yield, short reaction times, high turnover frequency, and catalyst durability are among the marked benefits of this synthesis method. Overall, the high catalytic activity of UMCM-1-NH2-F2C-Pd Nano composite may be due to the obtained high surface area and the synergistic features created between Lewis acidic Zn nodes and Pd ions.
