Abstract

Abstract: The structure of heptaalkylbenzenium ions has been investigated in the gas phase with complementary techniques, ie, chemical ionization mass spectrometry, alkylation of hexaalkylbenzenes by radiolytically generated cations, and collisionally induced dissociation mass spectrometry. The results allow us to assign the o-complex (Wheland intermediate) structure to the free, gaseous heptaalkylbenzenium ions, in agreement with ...
