We do not claim this to be a violation of the Woodward-Hoffmann rules, as these, focusing on the symmetry analysis of reactant and product, are consequently applied to structures that have symmetry elements. In contrast, the Dewar-Zimmerman interpretation applies to both symmetric and nonsymmetric transition-state structures. However, a topological orbital-mapping technique has been employed to show that the symmetry analysis can be replaced by a homeomorphic relationship between reactant and product topological spaces and that also applies to nonsymmetric molecules: see D. R. Kelsey, J. Comput. Chem. 1980,1, 3

In a basis orbital correlation diagram of a cyclically conjugated molecule, a phase inversion is denoted by an overlap of two individual orbital lobes with opposite signs. Two orbital phase inversions always annihilate and are equivalent to zero phase inversions in an MO with either the same number of nodal planes or a number of nodal planes incremented by one. A sign change inside an orbital (as in the delocalization pathway in the conrotatory transition state in 1,3,5,7-octatetraene, Figure lb) is not considered a phase inversion. Also see: M. J. S. Dewar, Angew. Chem. 1971, 83, 859; Angew. Chem. Int. Ed. Engl. 1971, 10, 761.

Woodward, in a 1966 lecture put it in the words: Out of the blue, it occurred to me that the coefficients of the terminal terms in the mathematical expression representing the highest occupied molecular orbital of butadiene were of opposite sign, while those of the corresponding expression for hexatriene possessed the same sign. From here it was but a short step to the geometric, and more obviously chemically relevant, view that in the internal cyclization of a diene, the top face of one terminal atom should attack the bottom face of the other, while in the triene case, the formation of a new bond should involve the top (or pari passu, the bottom) faces of both terminal atoms, quoted by R. Hoffmann, Angew. Chem. 2004, 116, 6748; Angew. Chem. Int. Ed. 2004, 43, 6586

The idea of Möbius aromatic transition states, namely those which have the Möbius strip topology, but do not involve forming or breaking of bonds, was invoked in 1999 (see ref. [2a], species 25a, pp. 143 and 144: the aromaticity of the bond rotation transition state was confirmed by a NICS value of -6.2 and a diamagnetic susceptibility exaltation of - 80.2 ppm cgs);

It is interesting to note that terms suprafacial and antara-facial lose their accustomed meaning for a Möbius system with purely laticyclic orbital overlap and with a π system without distinguishable faces. Please note that this is not homotopy (i.e. equivalence of faces).

Another, purely geometric index of aromaticity is the HOMA (harmonic oscillator model of aromaticity) index, which has proven very successful, for example, in the evaluation of the aromaticity of polycyclic aromatic compounds and which gives a value of + 0.88 for T..S. 2 (benzene has by definition a value of + 1). However, we think that the question of re-calibration of the model to account for the specific nature of Möbius aromatics should at least be considered, see a) J. Kruszewski, T. M. Krygowski, Tetrahedron Lett. 1972, 36, 3839;

This would be sufficient though from a quantum-mechanical perspective and to assess the presence of Möbius aromaticity itself, see Ref, 21q] and references cited therein

The forbiddenness in the Woodward-Hoffmann selection rules is of course not absolute, as for example, for some electronic transitions in molecules, where, however, symmetry forbidden transitions might also occur, albeit with lower probability.
