- Reaction of 3,5-Di-tert-butyl-4-hydroxybenzyl Acetate with Amines
-
3,5-Di-tert-butyl-4-hydroxybenzyl acetate reacts with primary and secondary amines to give mainly the corresponding benzylamines. Base-catalyzed transformation of 3,5-di-tert-butyl-4-hydroxybenzyl acetate into 2,6-di-tert-butyl-4-methylene-2,5-cyclohexadienone occurs to a small extent. The major product of the reaction of 3,5-di-tert-butyl-4-hydroxybenzyl acetate with aqueous ammonia is bis(3,5-di-tert-butyl-4-hydroxybenzyl) ether which is formed by the action of ammonium acetate liberated during the process.
