Abstract

We wanted to explore oxidation reactions where aromatization could act as a driving force for loss of hydrogen. Herein, we report the first examples of catalytic hydrogen-transfer reactions for the formation of benzimidazoles, benzoxazoles, and benzothiazoles. These heteroaromatic systems are commonly encountered groups in natural products,(8) pharmaceuticals,(9) agrochemicals,(10) and other effect chemicals, and new methods for their preparation are ...
