Preferential Activation of Primary C-H Bonds in the Reactions of Small Alkanes with the Diatomic MgO+ Cation

Original language description

The C-H bond activation of small alkanes by the gaseous MgO+center dot cation is probed by mass spectrometric means. In addition to H-atom abstraction from methane, the MgO+center dot cation reacts with ethane, propane, n- and isobutane through several pathways, which can all be assigned to the occurrence of initial C-H bond activations. Specifically, the formal C-C bond cleavages observed are assigned to C-H bond activation as the first step, followed by cleavage of a beta-C-C bond concomitant with release of the corresponding alkyl radical. Kinetic modeling of the observed product distributions reveals a high preference of MgO+center dot for the attack of primary C-H bonds. This feature represents a notable distinction of the main-group metal oxide MgO+center dot from various transition-metal oxide cations, which show a clear preference for the attack of secondary C-H bonds.
