Plant-aided Biosynthesized Heterogeneous Palladium Nanoparticles-Catalyzed Suzuki Coupling Reaction: A Review

Abstract

Plant-aided biosynthesis of palladium nanoparticles is a necessity nowadays to avoid toxic chemicals used in the synthesis of palladium nanoparticles in traditional methods. Palladium nanoparticles are used as a catalyst in the Suzuki coupling reaction. Traditional synthesis of palladium nanoparticles uses harmful chemicals, reducing agents, and solvents, creating toxic byproducts. The Suzuki coupling reaction is a key step in the formation of C-C bonds in organic synthesis. The Suzuki coupling reaction has numerous applications in the synthesis of pharmaceuticals, agrochemicals, etc. So, there is scope for developing an environmentally friendly and low-cost palladium nanoparticle catalyst for the Suzuki coupling reaction that reduces environmental pollution. The traditional Suzuki coupling reaction requires expensive and toxic ligands, solvents, and bases and also produces toxic byproducts. In this review article, we focus on plant-assisted biosynthesis methods for the production of palladium nanoparticles and their applications for the Suzuki coupling reaction.
