Pd/DNA as Highly Active and Recyclable Catalyst of Suzuki–Miyaura Coupling

Abstract

Pd/DNA catalysts were prepared in a mixed H2O/EtOH solvent using palladium precursors, Pd(OAc)2 and PdCl2, in different dosages and salmon fish sperm DNA. As prepared, the Pd/DNA contained Pd(II) and Pd(0) nanoparticles of various sizes and morphologies, depending on the preparation method. Pd/DNA efficiently catalyzed the Suzuki–Miyaura cross-coupling of various aryl bromides with phenylboronic acids. The catalyst was recovered by simple phase separation and then reused in seven consecutive cycles with a high activity.

Advances in Transition‐Metal Catalyzed Carbonylative Suzuki‐Miyaura Coupling Reaction: An Update

“…A. M. Trzeciak and his group [59] reported the synthesis of Pd/DNA nanoparticles and characterization by FT‐IR, TEM, XPS and XRD techniques. The Pd/DNA catalyst application was estimated by the carbonylative Suzuki‐Miyaura coupling between aryl bromides 49a and arylboronic acid 49b .…”

The effect of the DNA support on Pd/DNA catalyzed organic transformations

“…In this context, DNA-supported palladium catalysts (Pd/DNA) have been prepared and their catalytic activities have been performed in imination, 67 hydrogenation, 68,69 crosscoupling, [69][70][71] and carbonylation reactions (Fig. 1).…”

Comparing Separation vs. Fresh Start to Assess Reusability of Pd/C Catalyst in Liquid‐Phase Hydrogenation

“…Therefore, testing recovery and recycling functionalities is required in the case of newly prepared catalytic materials or advancing already available materials. To date, great efforts have been made to create recyclable nanostructured and supported catalysts for environmentally friendly processes of organic synthesis [8–18] . Obviously, the long‐term operation of the catalyst without loss of its activity and selectivity in a particular reaction shows the potential for its practical application.…”
