Large Hyperconjugation in Strained Systems
Abstract : Carbocations can appear as transient species, for instance, in elimination reactions and various rearrangements. Hyperconjugation (or conjugation) can then stabilize the cationic character and form a partial π bond. The effect of the electronic delocalization from strained substituents to a carbocation part was calculated. Very large hyperconjugation was found, sometimes more than 80 kcal mol-1, which is much larger than typical conjugation effects (56 kcal mol-1 for the allyl cation).
