ISOMERIC FLUOROBENZYL AND FLUOROTROPYLIUM CATIONS

The tendency for isomerization of toluene and cycloheptatriene molecular ions, and of benzyl and tropylium product ions, is substantially reduced by fluorine substitution, irrespective of position.This stabilization appears to be due to back-donation of electrons from fluorine, despite its high electronegativity.

Substituent Effect on the Stability of Benzyl Cation in the Gas Phase

Chloride ion affinities of substituted benzyl cations in the gas phase have been determined by means of an ICR mass spectrometer.The substituent effect has been analyzed in terms of the LArSr Eq., giving a p=13.6 and r+=1.31.
