Generation of polyfluoroaryl-fused H-pyrazolo[5,1-a]isoquinolines through a reaction of N'-(2-alkynylbenzylidene)hydrazide with polyfluoroarene.
Polyfluoroarene reacts with N'-(2-alkynylbenzylidene)hydrazide catalyzed by silver triflate in the presence of cesium carbonate, leading to polyfluoroaryl-fused H-pyrazolo[5,1-a]isoquinolines in good yields.
