✦ Synopsis

The Michael-addition of polyfluoroalkenoates with thiophenols in acetonitvile in the presence of Na- HC03 yielded the corresponding addition products, which were further treated with polyphosphoric acid (PPA) to give a series of new fluorine-containing thiochromones in good yields.

## Abstract A facile and general three‐step synthetic route towards unsymmetrical 9‐arylxanthenes was developed. The reaction sequence involves nucleophilic substitution of commercially available 2‐fluorobenzaldehydes with arenoxides, Grignard reaction of the resulting 2‐arenoxybenzaldehydes with a
