Synthesis and Reactions of 3-Iodo-4H-pyran-4-ones

3-Iodo-4H-pyran-4-ones have been synthesized in excellent yield by the reaction of acetylenic β-diketones with iodine monochloride and were converted into the corresponding 4H-pyran-4-thiones.The iodopyrones and thiopyrones gave with methylamine the respe
