30. Despite a certain lack of theoretical rigor in applying UB3LYP calculations to these open-shell singlets, we report these values for comparison with the results in the enyne allene series in refs 2a, 18, and 19. One can reach the same conclusions by comparing the triplet diradical energies.
31. For the zwitterion 4a±, we find a structure lower in energy than that reported in ref 19. We note that the wave function is unstable with respect to symmetry breaking for both 4± and 5 at the B3LYP level.

34. In the aza-Myers-Saito case, B3LYP/6-31G* calculations indicate that 4b± is a saddle point corresponding to the transition state for the interconversion of the two enantiomeric cyclic allenes 5b.
