聚合物Lin树脂与氯化碘作用得到载氯化碘Lin树脂。室温及CaCO3或NaHCO3存在下，该树脂在CH2Cl2和CH3OH溶液中，使芳胺、乙酰芳胺和酚碘化为相应的1-碘取代芳香化合物，产率为80.5%～94.0%。该树脂是一种反应条件温和，选择性好的活泼芳环碘化剂。Lin树脂可再生重复使用。

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.
