A [Cp*Ir(III)] complex is chemisorbed on the superacidic solid Brønsted acid sulfated zirconia (ZrS) to form a highly electrophilic supported Ir species (Ir-ZrS). The synthesis and characterization of Ir-ZrS is described including solid-state NMR spectroscopy. Ir-ZrS catalyzes deuterium incorporation into a variety of organic substrates through facile C–H activation using deuterated benzene as the deuterium source. Supporting the same complex on a non-sulfated support, such as zirconia or silica, does not lead to the same catalytic activity.
