Abstract: PURPOSE:To produce the titled compound useful as a synthetic intermediate for miticidal compound, medicine, etc., without producing by-product saving a fluorine source in high yield at a low cost, by using a fluorinated diaryl iodonium compound as a raw material and thermally decomposing the material in the absence of solvent. CONSTITUTION:A fluorinated diaryl iodonium compound of formula I (R and R are alkyl, halogen, nitro, alkoxy or acylamino; m and n are 0 or 1-5) is used as a raw material and thermally decomposed at 120-300 deg.C in the absence of solvent to obtain the objective compound of formula II (R is R and/or R ; l is m when R is R and l is n when R is R ). The starting compound of formula I is synthesized e.g. by reacting a corresponding halogenated diaryl iodonium compound with silver oxide and reacting the product with hydrofluoric acid.

Abstract: PURPOSE:To produce the titled compound useful as an intermediate for the production of an aromatic fluorine compound, easily at a low cot, by reacting a diaryl iodonium hydrogen sulfate with a hydrogen fluoride-donative substance in the presence of a basic barium salt. CONSTITUTION:The objective diaryl iodonium fluoride compound of formula II (e.g. diphenyl iodonium fluoride) can be produced by reacting (A) a diaryl iodonium hydrogen sulfate of formula I (R and R are alkyl, halogen, nitro, alkoxy or acylamino; m and n are 0 or integer of 1-5) (e.g. diphenyl iodonium hydrogen sulfate) with (B) a hydrogen fluoride-donative substance (e.g. anhydrous hydrofluoric acid, gaseous hydrogen fluoride, etc.) in the presence of (C) a basic barium salt (e.g. barium hydroxide) preferably in a polar solvent. USE:A synthetic intermediate for a fluorinated aromatic compound useful as an intermediate for insecticidal and miticidal agents and other agents.

Abstract: PURPOSE:To obtain the titled substance useful as an intermediate for the synthesis of an aromatic compound having a functional group such as halogen atom, amino group, etc., at a low cost, by using easily available aromatic compound and aromatic iodide as raw materials and reacting with a specific amount of concentrated sulfuric acid in the presence of an oxidization agent. CONSTITUTION:The objective compound of formula III can be produced by reacting (A) an aromatic iodide of formula I (R is alkyl, halogen, nitro, alkoxy or acylamino; m is 0 or 1-5; when m>=2, the R substituent groups are independently selected) with (B) an aromatic compound of formula II (R is alkyl, halogen, nitro, alkoxy or acylamino; n is 0 or 1-5; when n>=2, the R substituent groups are independently selected) and (C) 1-10 equivalent of concentrated sulfuric acid based on the component of formula I in the presence of (D) an oxidization agent such as potassium persulfate, preferably using a solvent containing acetic acid as a diluent at -20-+100 deg.C.
