Reaction of polyfluorinated phenols, naphthols, and their alkali metal salts with chlorine and bromine, Category: bromides-buliding-blocks, the publication is Zhurnal Organicheskoi Khimii (1973), 9(6), 1218-27, database is CAplus.

C6F5OH was unreactive toward Cl or Br in HOAc, aqueous HOAc, or H2O-Et2O at -10 to 0°. Anhydrous C6F5OK and Br in CCl4 yielded 44% 4-bromoperfluorocyclohexadienone (I, X = Br), which gave C6F5OH with Na2S2O3 or HBr; C6F5OK.2H2O gave I (X = Br, Cl) and their 2-haloisomers (II, X = Br, Cl) with Br in CCl4 and Cl in CH2Cl2, resp., with II predominating in both cases. 1-HOC10F7 yielded 87% 1-oxo-4-bromoperfluoro-1,4-dihydronaphthalene (III, X = Br) with Br in aqueous HOAc and a mixture of III (X = Cl) and its 2-chloro isomer (IV, X = Cl) with Cl in aqueous HOAc. 2-HOC10F7 and 2-KOC10F7 gave the resp. 2-oxo-1-haloperfluoro-1,4-dihydronaphthalenes (V) under identical conditions. 1-KOC10F7 and Br in CH2Cl2 gave III and IV (X = Br), with the latter predominating; IV (X = Br) was converted to III (X = Br) on standing. The III-IV ratio in the reaction products of 1-KOC10F7 with Br increased in the order of increasing solvent polarity: CCl4 < CH2Cl2 < MeNO2 < aqueous HOAc. 4-RC6F4OK hydrate (VI, R = Br) reacted with Cl in CCl4 to give 81% of the corresponding 2-chlorocyclohexadienones (VII). VI (R = H) gave 38% 4-BrC6F4OH with Br in CH2Cl2 via the corresponding intermediate 4-bromocyclohexadienone (VIII). VI (R = Me) treated with Br in CCl4 and Cl in CH2Cl2 gave the resp. VII and VIII, with VII predominating.
