On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides, and proceeds with minimal formation of the corresponding reduction products. A facilitated ligand modification process was shown to be critical to the success of the reaction.

β-Fluorovinamidium salt (2), readily prepared from N-(2,3,3-trifluoro-1-propenyl) trimethyl-ammonium iodide (1) and diethylamine, reacted with bifunctional hetero nucleophiles such as amidine and guanidine hydrochlorides in the presence of a base to afford regiospecifically monofluoronated pyrimidines 4 in good yields.The one-pot procedure starting from 1 was applicable for synthesizing heterocyclic compounds 4 in almost comparable yields.
