Phthalic Anhydride → 2-(4-Neopentylbenzoyl)-benzoic acid

Participants

Reaction Steps

We have found that this object is achieved by the novel compound 2-neopentylanthraquinone of the formula ##STR2## Furthermore, we have found a process for the preparation of 2-neopentylanthraquinone, wherein neopentylbenzene is acylated with phthalic anhydride by a Friedel-Crafts reaction to give 2-(4-neopentylbenzoyl)-benzoic acid and the latter is cyclized in the presence of a strong anhydrous acid to give 2-neopentylanthraquinone. We have also found that 2-neopentylanthraquinone is a catalyst for the preparation of hydrogen peroxide.
