Electrophilic nitration of triphenylamines as a route to high oxidation potential electrocatalysts. Polynitration, nitrodebromination, and bromine dance

The nitration of triphenylamine derivatives is facile, readily leading to an introduction of up to three nitro groups at room temperature. The nitration of 4,4′,4″-tribromotriphenylamine results in nitrodebromination on one or more rings and bromination at other sites.
