Diazotization-iodination of aromatic amines in water mediated by crosslinked poly(4-vinylpyridine) supported sodium nitrite

An Efficient and simple method for the diazotization of a wide range of aryl amines has been developed by using a polymer‐supported sodium nitrite. The diazotization of aryl amines occurred with crosslinked poly(4‐vinylpyridine)‐supported sodium nitrite, in the presence of concentrated H2SO4, at low...

Description
Summary:An Efficient and simple method for the diazotization of a wide range of aryl amines has been developed by using a polymer‐supported sodium nitrite. The diazotization of aryl amines occurred with crosslinked poly(4‐vinylpyridine)‐supported sodium nitrite, in the presence of concentrated H2SO4, at low temperature (0–5°C). The obtained diazonium salt, followed by treatment with KI in water at room temperature or at 60°C to produce a various of aryl iodides. The spent polymeric reagent can be regenerated and reused for several times without losing its activity. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
