Tackling aromaticity : The title reaction was accomplished by simultaneous activation of molecular hydrogen and the aromatic substrate by Pd/C and a Lewis acidic ionic liquid, respectively. Even benzene and C 60 fullerene were hydrogenated under ambient conditions (1 bar of H 2 at room temperature). An ionic hydrogenation mechanism (see scheme) is supported by characterization of a stabilized arenium intermediate.
