Annelation of perfluorinated heteroaromatic systems by 1,3-dicarbonyl derivatives

Reactions of various perfluorinated heteroaromatic substrates such as tetrafluoro-4-cyanopyridine, tetrafluoropyrazine and tetrafluoropyridazine with 1,3-dicarbonyl systems gave corresponding [5,6]-ring fused furo derivatives. Subsequent reactions of the [5,6] bicyclic scaffolds with nucleophiles gave some highly functionalised heteroaromatic systems.
