There is evidence that Cope Rearrangements may occur by as many as four distinct mechanisms, of which only one is the usual concerted mechanism (1). In 1972, Goldstein and Benzon reported the discovery of a second degenerate rearrangement of 1,5-hexadiene, occurring only at high temperature (250-300
The 3-aza-Cope rearrangements of 3-azoniahexa-1,5-diene (1), 3-azoniahex-1-ene-5-yne (3), and 3-azahex-1-ene-5-yne (5) were investigated up to the coupled-cluster level, CCSD(T), by using a valence triple-zeta basis set. Activation barriers and geometrical parameters of the transition states are pro
