Abstract

Just one step: Reactivity studies demonstrate that in the gas phase [Al2O3].+ clusters can efficiently conduct the direct conversion of CH4 into CH2O at room temperature (see scheme). The reaction mechanism is highly complex involving oxygen-atom transfer and a double hydrogen-atom transfer.
