Reactions of hidered phenols, such as 2,6-di-<I>t</I>-butyl-4-methylphenol, 3,5-di-<I>t</I>-butyl-4-hydroxybenzyl alcohol, and 2,6-di-<I>t</I>-butylphenol, with benzyltrimethylammonium tribromide were carried out in dichloromethane in the presence of water, <I>t</I>-butyl alcohol, or aqueous sodium hydroxide at room temperature. Sequential reaction processes were provided by the obtained products.
