Abstract
The structure and acidity of the dimethylhalonium ions were studied at the Density Functional Theory level of calculations. Results indicated that upon proton transfer to form the dimethylhalonium ylide, the C-X-C bond angle increases and there are modifications in the C-X bond lengths, indicative of hyperconjugation between the electron pair with the C-X antibonding orbital.
