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?
-
P-dibromobenzene, from phenol possibly.
-
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.
