1. NN-dichloroperfluoroaniline
2. Dropwise addition of perfluoroaniline (40.0 g, 219 mmo1) in AnalaR carbon tetrachloride (300 cm3 to a cold (−23 °C), stirred solution of t-butyl hypochlorite (48.0 g, 442 mmol) in the same solvent (700 cm3 followed, after 1 h, by the addition of a small crystal of iodine to the mixture provides N,4-dichloroperfluorocyclohexa-2,5-dienylidene amine in 78% yield (43.0 g, 171 mmol).
3. Only 80% conversion was achieved at 450 °C.
4. B. Al-Saleh, R. E. Banks, M. G. Barlow, G. R. Lomax, and M. Mamaghani work in progress.
5. Mechanisms for reactions of halogenated compounds. Part 2. Orienting effects of chlorine substituents in nucleophilic aromatic substitution
