The modified polyacrylonitrile fiber was used as carrier to prepare [AOFs-Pd(Ⅱ)].The cata-lytic performance of the Suzuki reaction on AOFs-Pd(Ⅱ)and halogenated aromatic hydrocarbons was investigated.Results showed that at room temperature,the yield of [AOFs-Pd(Ⅱ)]could reach 90%under following conditions:ethanol / water (V/V = 2 ∶ 1,30 mL)as solvent,potassium carbonate (10 mmol)as base,AOFs-Pd(Ⅱ)(0.1 g),boronic acid pinacol ester(6 mmol)and iodobenzene(5 mmol). The reaction also had a good adaptability on bromobenzene/its derivatives and brominated aromatic het-erocyclic.The catalyst could be easily separated from the reaction system after the reaction and used re-peatedly for six times.
