Abstract

Nucleophilic attack on hexafluorobenzene by sodium formanilides gave N, N′-diphenyl-2, 3, 5, 6-tetrafluorophenylene-1, 4-diamine as the main product at elevated temperature and N, N′-diformyl-N, N′-diphenyl-2, 3, 5, 6-tetrafluorophenylene-1, 4-diamine as the main compound at ambient temperature. Metallation of formanilide with lithium hydroxide instead of sodium hydride gave only 2, 3, 4, 5, 6-pentafluorodiphenylamine.
