Destabilized vinyl cations. An MO study of the influence of electron-withdrawing substituents

Ab initio (6-31G* and MP3/6-31G*//6-31G*) calculations show that vinyl cations substituted with α-CN, α-CHO and α-CF"3 groups are by 15-18 kcal/mol less stable than their saturated analogues and are among the least stable carbenium ions generated to date via solvolysis....
