Synthesis of palladated magnetic nanoparticle (Pd@Fe₃O₄/AMOCAA) as an efficient and heterogeneous catalyst for promoting Suzuki and Sonogashira cross‐coupling reactions

Abstract

Palladium supported magnetic nanoparticle (Pd@Fe3O4/AMOCAA) was easily prepared in the presence of Scrophularia striata extract and fully characterized by FT‐IR, SEM, VSM, TEM, TGA, XRD and EDAX. It was successfully employed as an easily separable and reusable effective heterogeneous catalyst classical Suzuki and Sonogashira cross‐coupling reaction. Sustainability of the methodology was reserved by easy recovery of the catalyst using an external magnet and reusing it for 7 times without appreciable loss of its catalytic activity.

SBA-15 Loaded with Methylene Blue Dye for Efficient and Low-Cost Decontamination of Water under Visible Led Light

“…Selecting suitable support is a critical step in improving photocatalytic performance. For instance, SBA-15, a silica mesoporous molecular sieve, captured much interest because of its well-2 ordered two-dimensional hexagonal structure, significant surface area (600-1100 m 2 /g), excellent adsorption capacity, high thermal stability, and, most notably, electron delocalization capacity provided by its framework, which allows it to be picked out rather than any other is chosen over to any other silicate substrate [9][10][11][12][13][14].…”

Biomass Waste-Derived Pd–PiNe Catalyst for the Continuous-Flow Copper-Free Sonogashira Reaction in a CPME–Water Azeotropic Mixture

“…Sonogashira cross-coupling is a widely useful synthetic tool allowing the introduction of an acetylenic moiety in a variety of molecular structures. − Since the seminal work by Sonogashira and Hagihara, the protocol has been largely studied and improved by exploiting the use of inorganic or organic bases under homogeneous or heterogeneous conditions and in the presence of a wide range of reaction media. − …”
