Article abstract of DOI:10.1016/0022-1139(93)02979-O

A number of 2-(polyfluoroalkyl)-thiochromones (4) and -chromones (5) have been synthesized in good to excellent yield by an intramolecular Friedel-Crafts acylation of the Z isomers of 3-(arylthio)- (2) and 3-(aryloxy)polyfluoro-2-alkenoic acids (3), which
