Conclusions
-
1.
3,6-Di-tert-butylpyrocatechol can be brominated and chlorinated with retention of the tert-butyl groups.
-
2.
The yield of the 4-bromo-3,6-di-tert-butylpyrocatechol that is formed during bromination is quite dependent on the nature of the solvent and the character of the counterion in the composition of the intermediate σ complex.
