The heats of formation of 13, 14, and 15 were obtained by use of the CAChe systems (Version 4.1.1, Oxford Molecular Group) AM1: M. J. S. Dewar, E. G. Zoebisch, E. F. Hearly, J. J. P. Stewart, J. Am. Chem. Soc. 1985, 107, 3902; 5a: 387.12538, 13: 29.70126, 14: 106.03925, 15: 65.75824, 16: 105.80957 kcal/ mol; PM3: J. J. Stewart, J. Comp.

As pointed out by one of the referees, there are great differences in the heats of formation of a single intermediate by different methods. These values are not absolute in nature but only of relative comparison.
