Participants

Reaction Steps

SnCl2 (5.8 g, 31 mmol) and 1.5 mL of conc. HCl (aq) were added to the solution of 4,4′-((3-Nitro-1,2-phenylene)bis (ethyne-2, 1-diyl))bis (2,3,5,6-tetrafluoropyridine), (18) (1.45 g, 3.1 mmol) in 30 mL of THF. The reaction mixture was stired for 1 day. After basification till pH>9 with NaOH (1.0 N solution), the product was extracted with dichloromethane. Solvent was evaporated and 0.4 g (31%) of the product aniline was purified by recrystallization: 1H-NMR (300 MHz, CDCl3) δ 7.29 (m, 1H), 7.09 (d, J=7.8 Hz, 1H), 6.87 (d, J=8.4 Hz, 1H), 4.58 (s, 2H)
