✦ Synopsis

Reactions of metal ions with benzene have been studied by the laser ablation-molecular beam method. The 1: 1 complex ion, M (C,H,) *, has been obtained for transition metals except for Nb by ion-molecule reactions of M+ and C,H,. The kinetic energy (KE) dependence studies have revealed that the slower portions in the wide KE distribution of M+ are effective in the reaction.

Collision stabilization of nascent complex ions has been shown by the experiments on pressure dependence. Nb gives Nb(CsHa)+, which has little KE dependence. The higher reactivity of transition elements as compared to typical elements is attributed to the d-n interaction.
