Abstract

Vanadium-arene complexes, Vn(arene)m (arene = benzene (C6H6), toluene (C6H5CH3), and fluorobenzene (C6H5F)), were synthesized by the reaction of laser-vaporized vanadium atoms with arene vapor. Both the analysis of the mass spectra and the measurements of their ionization energies indicate that both Vn(C6H5-CH3)m and Vn(C6H5F)m, clusters take a multiple-decker sandwich structure similar to the structure of Vn-(C6H6)m clusters. The relative reactivity between benzene and toluene toward vanadium was also determined; toluene is 4 times as reactive as benzene for V1(C6H5CH3)1/V 1(C6H6)1 production and 2 times for V1(C6H5-CH3)2/V 1(C6H6)2 production because of reactivity enhancement of the electron-donating ring substituent. In the case of the Vn(C6H5F)m cluster, it is found that the electron-withdrawing ring substituent of fluorobenzene results in much less reactivity than is observed for benzene and toluene.
