Summary

  1. 1.

    The action of free bromine on 2,6-dialkyl-4-bromophenols in presence of proton acceptors leads to the formation of o-quinobromides (2,6-dialkyl-2,4-dibromo-3,5-cyclohexadien-1-ones).

  2. 2.

    The stability of the o-quinobromides is related to their rearrangement into their isomers of p-quinonoid structure (2,6-dialkyl-4,4-dibromo-2,5-cyclohexadien-1-ones).

  3. 3.

    A study was made of the behavior of the quinobromides in presence of acid agents and when heated.
