Surface functionalization of magnetic nanoparticles via palladium‐catalyzed Diels‐Alder approach

Abstract Metal nanoparticles are currently being used as substantial catalysts for a number of classical chemical transformations. In contrast, performing novel biochemical reactions with the help of nano‐organocatalysts is highly underdeveloped area in chemical synthesis. In order to prepare an efficient nano‐organocatalyst, facilitated stable covalent bonding would be achieved by using Diels‐Alder reactions on the surface of magnetic nanoparticles. Herein, we report the synthesis of magnetic nano‐organocatalysts by using Fe 3 O 4 nanoparticle coated by SiO 2 network and functionalized with vinylsilane, as dienophile moiety of Diels‐Alder reactions. In this work, palladium(II) is used as an instrumental catalyst for Diels‐Alder reaction, as well.
