摘要：

Cationic gold catalyzes the title reaction in strong acid solvents with SeVI as the stoichiometric oxidant. At 180°C and 27 bar of CH4 turnover numbers of about 30 and methanol concentrations of 0.6 M have been observed with selectivities >90%. DFT calculations indicate that cationic AuI and AuIII are both viable catalysts that operate by electrophilic C-H activation and oxidative functionalization (see picture).
