Hi all:

I need to brominate the acetyl group of
4-acetyl-2,6-di-t-butylphenol
[3,6-di-t-butyl-4-hydroxyacetophenone]. Tried bromine
in ether with/without light or AlCl3 and also with
CuIIBr2 in EtOAc. Only partial bromination. One
russian patent mentions bromination at 120 oC in
n-octane under light bulb. Any
alternatives/suggestions?
Thanks in advance
