Aerobic C–H functionalization of benzene and a series of electron-rich and electron-poor arenes has been demonstrated using a Pt(II) aqua complex supported by a sulfonated CNN-chelating pincer ligand in wet 2,2,2-trifluoroethanol (TFE) solutions at 20 °C and ambient pressure of air or O2. The reaction results in Pt(IV) aryl hydroxo complexes and a Pt(IV) trifluoroethoxo complex as two major products, in a 1:1 molar ratio, along with minor Pt(II) products of the arene and pincer ligand oxidative C–C coupling.
