High-level ab initio molecular-orbital calculations indicate that the only C2H4 2+ isomer likely to be observable in the gas phase is the perpendicular ethylene dication (1). Other C,H:+ isomers lie higher in energy with extremely small barriers for collapse to 1.
The enthalpy of solvation in sulfolane of the gaseous protonated hydronium dication is estimated as -628 kcaYmo1 at 298 K. Using literature data, a value AW'= -2 12 kcal/mol is calculated for the reaction H,O+ +H+ +H,O'+ (in sulfolane), supporting the thermodynamic existence of H,02+ in sulfolane so
