Reaction Steps
To a reaction vessel, 0.74 g (2.50 m mol) of pentachloronitrobenzene, 1.77 g (13.00 m mol) of DFI, and 25 ml of acetonitrile were charged and reacted at 84° C. for 2 hours in a nitrogen atmosphere. After finishing the reaction, formation of dichlorotrifluoronitrobenzene (master ion, 245, master ion +2 247, master ion +4 249, base peak 245) was confirmed by GC-MS measurement on the reaction mixture, and the yield was 28.0% by GC analysis. Formation of trichloro-difluoronitrobenzene (master ion 261, master ion +2 263, master ion +4 265, base peak 205) was also confirmed and the yield was 11.3%. Formation of tetrachlorofluoronitrobenzene (master ion 277, master ion +2 279, master ion +4 281, master ion +6 283, base peak 221) was further confirmed and the yield was 9.0%.
