A selective and mild method for the benzylic fluorination of aromatic azaheterocycles with Selectfluor is described. These reactions take place by a previously unreported mechanism, in which electron transfer from the heterocyclic substrate to the electrophilic fluorinating agent Selectfluor eventually yields a benzylic radical, thus leading to the desired C?F bond formation. This mechanism enables high intra- and intermolecular selectivity for aza-heterocycles over other benzylic components with similar C?H bond-dissociation energies.

The reaction of sym-triazine with the hydrochlorides of N-unsubstituted enaminones gives mixtures of 4-alkyl-5-acyl(ethoxycarbonyl)pyrimidines and 2,6-dialkyl-3,5-diacyl(ethoxycarbonyl)pyridines.The reaction mechanism was studied by means of the 15N-labelled compounds.
