摘要：NOVELTY - A highly efficient ionic liquid crosslinked polystyrene supported palladium catalyst (I) is claimed. USE - Highly efficient ionic liquid crosslinked polystyrene supported palladium catalyst for use in synthesis of biaryl compounds (claimed) and Suzuki coupling reaction for synthesizing pharmaceuticals. ADVANTAGE - The highly efficient ionic liquid crosslinked polystyrene supported palladium catalyst is manufactured by a simple process, and enables to manufacture biaryl compounds with high yield using reduced amount of the catalyst under mild reaction conditions and by a simple process. The catalyst can be recycled efficiently. DETAILED DESCRIPTION - A highly efficient ionic liquid crosslinked polystyrene supported palladium catalyst of formula (I) is claimed. n=1-8; R2-=R1- or X-; R1=PF6, BF4, CF3COO, CH3COO or CF3SO3;and X=I, Br or Cl.
