Several 4H-chromen-4-ones with different substituents at 3-position, including phenyl, hydrogen and halogen were synthesized and the mechanism of the related unexpected products was discussed. This work will not only profit further modification on 3-position of parent structure but also enrich the chemical characteristics of this kind of compounds.

Key words: substituted 4H-chromen-4-one, cyclization, unexpected reaction
