A regioselective pathway for the preparation of xanthones from 2-bromofluorobenzenes and salicylaldehydes has been developed. The reaction proceeded through palladium-catalyzed acylation-SNAr sequence. Good to moderate yields of the desired xanthones were prepared in one step. Based on the results of control experiments, a possible reaction mechanism has been proposed.
