Vinylic trifluoromethyl triflones, in particular cyclic ones, constitute potentially valuable building-blocks for further syntheses. Their uses in Diels-Alder cycloadditions as dienophiles or dienes led only to moderate yields of expected products. However, under fluoride activation, they afforded unexpected tricycle compounds.

gem-Difluoro-1,7-enyne amides are suitable building blocks for the synthesis of difluorodihydropyridinones via a ring-closing metathesis reaction, and of 4,4-difluoro-3-oxoisoquinolines through a ring-closing metathesis–enyne metathesis tandem reaction. These products, in turn, undergo a Diels–Alder reaction to yield heterotricyclic systems in moderate to good yields.
