Synthesis of Diamino Benzoquinones using Facile and One-Pot Chemical Oxidative Method

摘要

An efficient synthesis of diamino benzoquinone, beginning from catechol derivatives and hydroquinone with azide ion was developed in the presence of potassium ferricyanide as an oxidizing agent (Decker oxidation), the results of which revealed the participation of azide ion in Michael addition reactions with benzoquinones yield in situ. This study has made one-pot oxidative method possible for diamino benzoquinones synthesis.
