A metal‐free, one‐potsynthesis of 1,2‐naphthoquinone was accomplished from 2‐naphthol by utilizing economically cheap NBS under open air conditions. Initial formation of 1,1‐dibromonaphthalen‐2‐one and subsequent transformation afforded the 1,2‐naphthoquinone. This oxidation was completed within 30 min and had broad substrate scope. Moreover, this system tolerated heterocyclic systems and was also
