Phosphonium resin reacted with iodine chloride to give iodine chloride supported on phosphonim resin. The resin reacted with aromaticc amines、acetanilides and phenols in dichloromethane and methanol in the presence of calcium carbonate or sodium biscarbonate at room tempture to give mono iodo - substituted aromatic compounds. The yields were 80.5%~94.0%. The resin was a mild yet effective iodinating agent for active aromatic rings with good selectivity. The phosphonium resin can be reused after treatment with iodine chloride.
