    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: PROBLEM TO BE SOLVED: To provide a palladium catalyst for carbon-carbon bond forming reaction which is highly active, facilitates separation and recovery of catalyst after the completion of liquid phase reaction, hardly causes the degradation of activity even when utilized repeatedly and can be easily produced, and to provide a production method of olefin group-substituted aromatic compound using the palladium catalyst. SOLUTION: The olefin group-substituted aromatic compound expressed by the formula (3) is produced with high yield by reacting an aromatic compound expressed by the formula (1) with an olefin compound expressed by the formula (2) in the presence of the palladium catalyst prepared by depositing a palladium compound and a fused salt having a fusing point of ≤150°C on an inactive porous metal oxide carrier, and a base.
