Abstract

The gas-phase reactivity of tungsten cations with ethylene was investigated by means of Fourier-transform ion cyclotron resonance mass spectrometry. The ethylene adsorbs on the W⁺ with partial dehy drogenation, forming W (C₂ H₂)_n⁺ cluster ions. Up to nine ethylenes can be consecutively added, n = 1-9. Collision-induced dissociation (CID) experiments provide evidence that a dehydrogenative oligomerization and formation of benzene takes place on the tungsten cation. The dominating fragmentation channel of the WC₆H₆⁺ ion results in appearance of the bare metal ion, suggesting that a C₆H₆ fragment, most likely benzene, was formed.
