General description

N-Hydroxytetrachlorophthalimide (TCNHPI) is an aryl-tetrahalogenated N-hydroxyphthalimide derivative. In combination with 1,4-diamino-2,3-dichloroanthraquinone (DADCAQ), it forms an efficient catalytic system for the oxidation of aromatic hydrocarbons using molecular oxygen under metal-free and aerobic conditions.

Application

New reagent enabling the electrochemical allylic C-H oxidation reaction developed by the Baran group. This method provides a scalable and sustainable alternative to current strategies based on toxic reagents or precious metals.
