Disubstitution on hexafluorobenzene with formanilides
摘要:
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.
