Dear all,

I would like to know If any has experience with bromination in harsh
conditions, using sealed tube at high temperature. I found one procedure
concerning the bromination of an electronically poor aromatic (pyridinium
derivative) which must be done by heating during 3 days at 180C. The
bromine’s boiling point is 58.7C, which means a very high pressure in the
tube at 180C. So does anyone know how to make such reaction in a safe way,
and which kind of tube may resist to such pressure?

Regards

Bel
