Highly water-dispersible magnetite nanoparticle supported-palladium–β-cyclodextrin as an efficient catalyst for Suzuki–Miyaura and Sonogashira coupling reactions

Abstract

We reported here a novel highly water-dispersible and recoverable magnetite supporting a palladium–β-cyclodextrin complex as an efficient catalyst in Suzuki–Miyaura and Sonogashira carbon–carbon coupling reactions. The magnetite nanoparticle supporting catalyst was characterized by FT-IR, CHN, EDS, TGA, XRD, TEM and VSM. The prepared catalyst displayed excellent activity for a wide range of substrates in aqueous solution under mild reaction conditions. The reusability of the magnetite supporting palladium–β-cyclodextrin nanocatalyst was successfully examined five times with a slight loss of catalytic activity.
