Article abstract of DOI:10.1021/jo00232a039

β-Chloroarylidenemalonates I have been transformed into β-(aryloxy)arylidenemalonates II.The ring closure of II in polyphosphoric acid leads to ethyl flavone-3-carboxylates and related compounds III.Hydrolysis of II gives β-(aryloxy)arylidenemalonic acids
