Vibrationally assisted tunnelling (VAT) in a 1,5 hydrogen shift?
Abstract
Vibrationally assisted tunnelling (VAT), kinetic isotope effect, and MINDO/3 calculations are reported for the 1,5 hydrogen migration of penta-1,3-diene; from these calculations it is demonstrated that tunnelling affects the kinetic isotope effect of this rearrangement and that the 1,5 shift should proceed via VAT almost exclusively at 498 K.
