Hello,
Can anyone please tell me the methods for the synthesis of  Dibromobenzene. It is very hard to find this data on the internet.

Which isomer?

In addition to the "what isomer" question, what starting material are you wanting to use?

[sprotz]

P-dibromobenzene, from phenol possibly.

[agrobert]

From benzene, Br2 HOAc. To get bromobenzene.  Then ZnBr2 to get p-bromobenzene as the major isomer.

Or from aniline, NBS, HOAc to get p-bromoaniline.  Then diazotonization of aniline with NaNO2 and subtitution with NaBr to get p-bromobenzene.

From phenol is tricky.  Give it a shot?

Thanks, that information more than helped.
