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.

Electrochemical Allylic C–H Oxidation with N-Hydroxytetrachlorophthalimide (TCNHPI)

Professor Phil Baran and coworkers have developed a new reagent, N-Hydroxytetrachlorophthalimide (ALD00564), which provides a cheap, scalable, and safe synthetic alternative to highly used transformations like allylic oxidations, as well as Negishi and Suzuki–Miyaura type cross-coupling reactions.

The Baran Group works with Sigma-Aldrich in providing a portfolio of zinc-based reagents promoting difluoromethylation, trifluoromethylation, trifluoroethylation and isopropylation of aryl and heteroaryl motifs. Baran’s lab has also helped introduce a portable desaturase (Tz0Cl), which promotes the installation of alcohol and amine groups and leaves behind a highly useful tosyl group for further transformations.
