The Synthetic Routes of 2,7-DibroMo-triphenylene

The synthesis of 2,7-dibromomethyl-triphenylene is an important process in the chemical industry, as this compound is commonly used as a raw material for the production of a variety of chemicals and materials.
There are several synthetic routes that can be used to produce 2,7-dibromomethyl-triphenylene, and the choice of route will depend on the desired yield, purity, and cost of the final product.

One of the most common synthetic routes for 2,7-dibromomethyl-triphenylene involves the reaction of iodomethane with 2,7-dimethyl-triphenylene in the presence of a Lewis acid catalyst, such as aluminum chloride.
This reaction involves the formation of a Grignard reagent, which is then treated with an oxidizing agent, such as potassium permanganate, to introduce the bromine atoms.
The product is then treated with an alcohol, such as methanol, to remove the halogen atoms and form the desired product.

Another synthetic route for 2,7-dibromomethyl-triphenylene involves the reaction of 2,7-di-tert-butyl-triphenylene with bromomethane in the presence of a Lewis acid catalyst, such as ferric chloride.
This reaction is carried out under conditions similar to those used in the previous route, and the resulting product is treated with an alcohol to remove the halogen atoms and form the desired product.

A third synthetic route for 2,7-dibromomethyl-triphenylene involves the reaction of 2,7-di-tert-butyl-triphenylene with bromine in the presence of a Lewis acid catalyst, such as zinc chloride.
This reaction is also carried out under conditions similar to those used in the previous routes, and the resulting product is treated with an alcohol to remove the halogen atoms and form the desired product.

Regardless of the synthetic route used, the resulting 2,7-dibromomethyl-triphenylene is typically purified by crystallization or by recrystallization from a suitable solvent.
The purified product is then used as a raw material for the production of a variety of chemicals and materials, such as dyes, electrolytes, and polymers.

In conclusion, the synthetic routes for 2,7-dibromomethyl-triphenylene are many and varied, and the choice of route will depend on the desired yield, purity, and cost of the final product.
Regardless of the route used, the resulting product is typically purified by crystallization or by recrystallization from a suitable solvent, and is then used as a raw material for the production of a variety of chemicals and materials.
