Synthesis of selenium-containing derivatives of para-bromopropyl-substituted phenols

Resumo

The dynamics of changes in the composition of the reaction mixture during the reaction of Na₂SeSO₃ and bromopropyl-substituted phenol in 50% aqueous ethanol and under the conditions of decreasing EtOH concentration in the reaction medium was studied. Convenient methods for the synthesis of 3-(4-hydroxyaryl)propyl selenosulfates and the corresponding diselenides were proposed. Symmetrical and unsymmetrical selenides (derivatives of alkylated phenols and pyrocatechol) were synthesized.
