Benzoylacetanilides from 2-phenyl-4(1H)-quinolones when acted on by an equimolar proportion of AlCl3, AlBr3 or SnCl4, BF3 affords the difluoroborane derivative of the anilide. Complexes of the anilides with AlBr3 and SnCl4 were prepared and heated to give the 4(1H)-quinolones. A mechanism for the anilide-quinolone transformation is suggested.
