Ag, Au and ZrO₂@reduced graphene oxide nanocomposites; Pd free catalysis of suzuki-miyaura coupling reactions

Abstract Suzuki coupling is a widely used, well-studied and versatile method in synthetic chemistry for development of C–C bonds where palladium-based catalysts have been used extensively the reaction to date. We report Suzuki-cross-coupling formation between aryl halides phenylboronic acid by using Metal/metal oxide@Reduced graphene oxide nanocomposites being efficient, simple cost-effective. In this work, plant mediated synthesis silver, gold zirconia nanoparticles doped Reduced Graphene Oxide reported 30 mg each resulted C-C bond achieving percentage yield comparable catalyst as standard series reactions, attaining highest with silver based catalyst. The demonstrated high catalytic activity over three cycles recycling no loss. Bromoaryl are coupled together increased surface area reduced substrate, which also exhibits enhanced reactivity toward other chemical reactions. XRD, FTIR UV–vis analyses were describe synthesized Using devised technique, various substituted successfully modest yields desired biphenyls.
