Abstract: 
An efficient method for the synthesis of range of biaryl through Suzuki-Miyaura cross-coupling of a variety of aryl boronic acids with aryl halides employing highly water dispersible, magnetically separable, palladium tagged, magnetic nanoparticle supported, ionic liquid phase catalyst (Pd-SILP-Fe3O4@SiO2) in water under aerobic conditions has been developed. This nanocatalyst exhibited high thermal stability, high catalytic efficiency, high turnover frequencies (TOF), compatibility in aqueous systems, easy magnetic recovery, and reusability up to 6th run. The major advantages of this method are mild reaction conditions, easy set-up, easy workup, low Pd loading (0.00084 mol% of Pd), higher yields, and use of water as a green solvent, which makes it both environmentally and economically appealing.
