several methods for the ortho selective arylation of fluoroarenes, meta-functionalisation has never been achieved. We report a new methodology, based on the traceless directing group relay concept, leading to the first meta-selective (hetero)arylation of fluoroarenes. In this strategy, CO2 is introduced as a transient directing group, to control a Pd-catalysedarylation meta to the fluoro functionality,
