Teaching old compounds new tricks: DDQ-Photocatalyzed C-H
Amination of Arenes with Carbamates, Urea and N-Heterocycles

Das, Somnath ; Natarajan, Palani ; König, Burkhard



Abstract

The C-H amination of benzene derivatives was achieved using DDQ as photocatalyst and BocNH(2) as the amine source under aerobic conditions and visible light irradiation. Electron-deficient and electron-rich benzenes react as substrates with moderate to good product yields. The amine scope of the reaction comprises Boc-amine, carbamates, pyrazoles, sulfonimides and urea. Preliminary mechanistic ...
