Ammonium iodide in open air decomposes to ammonia and iodine. The in situ
generated iodine has been used for cyclization of 2?-hydroxychalcones to
corresponding flavones under solvent free conditions with good to excellent
yields. This method would serve as an attractive alternative to the existing
methods for synthesis of flavones and use of toxic molecular iodine is
avoided.
