3, 5-Di-tert-butylphenol (I) was synthesized by two independent routes. It was possible to isolate a mononitro and a dinitro product. It was not possible to isolate a trinitrated product (3, 5-di-tert-butylpicric acid). Bromination of I gave the dibrominated product, and chlorination of I gave a dichlorinated product and a tetrachloro product; the latter was shown to possess the dieneone structure.
