Abstract

original image

The first catalytic oxidative activation of methane in the gas phase employs high-vacuum conditions and Pt+ ions generated by laser desorption. In the presence of O2 the initially generated Pt+[BOND]CH2 is oxidized to formic acid (65%), formaldehyde (25%), and methanol (10%). The picture on the right shows the most important part of the complicated catalytic cycle.
