Phenylmagnesium chloride has been used for the conversion of selected nitroarenes into nitrenes. Their insertion into a neighboring sp(2) C-H bond yielded functionalized heterocycles. A novel and mild synthesis of polyfunctional benzimidazoles and indoles is described.

Phenylmagnesium chloride effectively converts functionalized nitroarenes into nitrenes, leading to the mild synthesis of polyfunctional benzimidazoles and indoles.
