Hi Maruthinath,

Synthesis of α,α′-Dibromo-p-xylene may cost you more than buying the actual product via Sigma-Aldrich if you are looking forward to use it as a precursor for something else.

We are getting lesser price than aldrich outside now we are plnning to prepare anyhow thanks alot

I've tried with N-bromosuccinimide, benzoyl peroxide and carbon tetrachloride but the yield was only around 20%

thanks alot  mam.

we prepared in our lab we got 10% pure α,α′-Dibromo-p-xylene only madam  Olga Kaczerewska can you give brief information, the mole ratio NBS and  benzoyl peroxide. And did you add above both single lot or portion wise and how did you purified it

I used 0,04mol of NBS and 5,9mmol of benzoyl peroxide. I put everything todether. Purified by cristallization using methanol.

Thanks  madam Olga we tried now we got the same
