Description
Summary:Herein we prepared the novel LaF 3 ·Pd nanocatalyst characterized by XRD and TEM analysis. The nanocatalyst was applied in Suzuki coupling reaction for the synthesis of biaryls in aqueous medium from readily available aryl halides (bromides and iodides) and substituted phenylboronic acids in the presence of K 2 CO 3 as the base at 70 °C. The present method is capable of giving the C-C coupled product in good to excellent yields (up to 97%). The reactions were conducted under green conditions in aqueous medium and the nanocatalyst used in this study was recyclable. The recyclability and reusability of the catalyst was checked for seven consecutive cycles without significant loss in reactivity. A green and sustainable approach has been developed using a recyclable and reusable LaF 3 ·Pd nanocatalyst. This catalyst has been applied in the synthesis of biaryls in good to excellent yields via Suzuki coupling in aqueous medium.
