Biosynthesis of palladium nanoparticles using Poplar leaf extract and its application in Suzuki coupling reaction

A green route for the synthesis of palladium (Pd) nanoparticles (Pd NPs) employing Poplar leaf extract as a reducing and capping agent is described. The as‐prepared Pd NPs are spherical with a face centred cubic structure, a particle distribution of 2.2–6.8 nm and an average particle size of 4.2 nm. The application of this catalyst toward homogeneous Suzuki coupling reactions was investigated. The Pd NPs afforded a yield of 98.86% in the Suzuki coupling reaction of 4‐bromotoluene with phenylboronic acid using 0.01 mmol% of the catalyst at 60°C for 30 min under an air atmosphere.Inspec keywords: palladium, nanoparticles, nanofabrication, particle size, catalysts, organic compounds, nanobiotechnologyOther keywords: biosynthesis, palladium nanoparticles, Poplar leaf extract, green route, reducing agent, capping agent, face centred cubic structure, particle size, catalyst, homogeneous Suzuki coupling reactions, 4‐bromotoluene, phenylboronic acid, size 4.2 nm, temperature 60 C, Pd
