Abstract
A simple and efficient method for the synthesis of biaryls by fluoride-free Hiyama coupling using Pd/Fe3O4 as the catalyst under aqueous conditions is applicable to a wide range of aryl bromides and aryl siloxanes. High catalytic activity, ease of recyclability using an external magnetic field and use of water as the solvent are additional eco-friendly attributes of this catalytic system.
