Alinezhad, Heshmatollah; Pakzad, Khatereh published the artcile< C-S Cross-coupling reaction using novel and green synthesized CuO nanoparticles assisted by Euphorbia maculata extract>, Recommanded Product: 2-(Phenylthio)ethanol, the main research area is copper oxide nanoparticle green catalyst preparation; aqueous Euphorbia maculata copper sulfate extract green biosynthesis; thioether preparation green chem; thiol aryl halide cross coupling CuO nanoparticle catalyst.
In the present study, biosynthesis of CuO nanoparticles using a rapid, eco-friendly, cost-effective and efficient method was reported employing aqueous Euphorbia maculata extract as mild, renewable and non-toxic reducing and capping agents without adding any surfactants. This biogenic and green method had some benefits compared to conventional phys. and chem. methods. The biosynthesized CuO NP displayed a color change pattern (from sky blue to black) on preparation and presented its resp. broad peak at 365 nm, which was analyzed by UV-vis spectroscopy. Using FT-IR anal., biomols. in E. maculata extract which were responsible for bioreduction activity and synthesized CuO NP, were identified. XRD, EDX and FESEM results confirmed successful synthesis of CuO nanoparticles of 18 nm sizes, with spherical and sponge crystal structure. Catalytic activity of biosynthesized CuO NPs was studied in C-S cross-coupling reaction of thiols with aryl halides. This method had the advantages of high yields, easy work-up, and simple reusability. The recovered CuO NP could be reused four times without any considerable loss of its catalytic activity.
