Direct aromatic-ring amination by aqueous ammonia with a platinum loaded titanium oxide photocatalyst

摘要

Active species generated from aqueous ammonia with a platinum-loaded titanium oxide photocatalyst can selectively aminate the aromatic ring of benzene and some substituted benzenes. Anilines are important chemical intermediates for the production of dye, resin, medicine, etc. and mainly synthesized by multi-step processes consisting of aromatic-ring nitration using mixed acid and successive hydrogenation of the nitro group at high temperature.
