The method is characterized by comprising the following steps: taking m-chloronitrobenzene as a raw material, carrying out high-temperature chlorination reaction, nitration reaction and fluorination reaction to obtain 2,4 - 2,4 -difluorobenzene and carrying out a methoxylation reaction with m-difluorobenzene as a raw material and carrying out methoxylation reaction to obtain m-fluorobenzyl ether; and the hydrogenation catalyst is a porous alumina loaded NiO-Co222O3-MoOO3 composite catalyst. The method disclosed by the invention is simple in process and high in product yield. (by machine translation)
One-Pot C?H Functionalization of Arenes by Diaryliodonium Salts

supporting information, p. 8928 - 8932 (2016/07/26)
A transition-metal-free, mild, and highly regioselective synthesis of nitroarenes from arenes has been developed. The products are obtained in a sequential one-pot reaction by nitration of iodine(III) reagents with two carbon ligands, which are formed in situ from iodine(I). This novel concept has been extended to formation of aryl azides, and constitutes an important step towards catalytic reactions with these hypervalent iodine reagents. An efficient nitration of isolated diaryliodonium salts has also been developed, and the mechanism is proposed to proceed by a [2,2] ligand coupling pathway.

Paragraph 0161-0162, (2014/06/24)
A method for producing a nitrobenzene compound represented by general formula (2), wherein R1 and R5 are the same or different, and each is a halogen atom or another functional group, and R2, R3, and R4 are the same or different, and each is a hydrogen atom or another functional group, comprises oxidizing an aniline compound represented by general formula (1), wherein R1, R2, R3, R4, and R5 are the same as described above, with hydrogen peroxide in the presence of a tungsten compound under an acidic condition, followed by oxidation with hydrogen peroxide under a neutral to alkaline condition.
