-
Paragraph 0024-0037, (2021/08/25)
The invention discloses a preparation method of 2 -bromoiodobenzene, which comprises the following steps: under the protection of inert gas, adding triphenylphosphine to an organic solvent, adding organic amine to 50 - 75 °C DEG C under stirring conditions, and stirring 1 - 2 hours. Then iodine is added to 60 - 80 °C thermal insulation stirring 2 - 4.5 hours. Finally 2 - bromophenol was added and stirred 5 - 10 hours under reflux. The resulting reaction solution was naturally cooled to ≤ 40 °C, sodium methoxide was added, stirred and filtered, and the filtrate was post-treated to give 2 - bromoiodobenzene. 2 - Bromoiodobenzene is prepared by the method disclosed by the invention, and has the characteristics of simple process and high product yield.

A convenient, efficient and practical visible-light-induced decarboxylative iodination of aromatic carboxylic acids has been developed, and the corresponding aryl iodides were obtained in good yields. The method shows some advantages including the use of readily available aromatic carboxylic acids as the starting materials, simple and mild conditions, high efficiency, wide substrate scope and tolerance of various functional groups.

The reaction of 1,2-dibromobenzenes with chlorotrimethylsilane efficiently proceeded in the presence of Mg and LiCl in DMI under mild conditions, giving 1,2-bis(trimethylsilyl)benzenes in good to high yields. The reaction of 1,2-dibromobenzenes with chlorodimethylsilane under the same conditions afforded the corresponding 1,2-bis(dimethylsilyl)benzenes in high yields. Functional group transformations of 1,2-bis(trimethylsilyl)benzene were conducted to demonstrate the synthetic utility.
