摘要
A combined theoretical and experimental study on the Pt+-mediated activation of methane is presented. Dehydrogenation of CH2 by thermalized Pt+ cations (Pt++ CH4 reversible arrow PtCH2++ H-2) proceeds along a doublet ground state potential energy surface and is found to be reversible under the conditions of Fourier transform ion-cyclotron resonance mass spectrometry. The recently reported oxidation of the cationic platinum carbene PtCH2+ by O-2 produces electronically excited Pt+ cations, which are detected in the F-4(9/2) state by means of charge-transfer bracketing experiments.
