What is it about?
The use of elemental bromine in reactions has many dangers and disadvantages, so we report an efficient and regioselective solid reagent for the bromination of various organic substrates such as phenol and aniline or its derivatives. This reagent can be recovered and reused several times. The name of this reagent is o-Xylylene bis(triethyl ammonium tribromide) (OXBTEATB) as a more useful brominating and regioselective catalyst than the liquid bromine.

Why is it important?
This reagent named o-Xylylene bis(triethyl ammonium tribromide) (OXBTEATB), due to its crystalline nature, lack of toxicity, availability, regioselectivity, eco-friendliness, and their relative stability under atmospheric conditions, is preferred over some liquid brominating agent. Therefore, with this reagent, work-up and purification process become more comfortable.
Perspectives
The use of this recyclable solid catalyst is based on the principles of green chemistry and , so we hope this article makes an environmental friendliness way to reduce environmental pollution.
