摘要：

An experimental study of protonated benzene in the gas phase in reported, stimulated by the recent suggestion of a face centered pi-complex structure as the most stable form of protonated benzene. C6HxD(7-x)(+) ions have been formed either by protonation of C6D6 by H3O+ and ensuing H/D exchange reactions with H2O or by the mirror isotope reaction of C6D6 With D3O+/D2O. Their assay by two sampling methods, H+/D+ transfer to strong bases and collisionally activated dissociation, was found consistent with a sigma-complex species. (C) 1997 Elsevier Science B.V.
