Orbital correlation diagram benzene valence isomerization

Figure 7.44. Benzene-dewarbenzene valence isomerization a) orbital correlation diagram (Cj, symmetry) and b) state correlation diagram, devised with the help of Table 7.5 and experimental state energies.

The experimental results on valence isomerization of benzene can be rationalized by means of correlation diagrams that were first discussed for hexa-fluorobenzene by Haller (l%7). The orbital correlation diagram for the conversion of benzene to dewarbenzene (Figure 7.44a) has been constructed on the basis of a classification of the benzene Jt MOs according to C , symmetry. The full symmetry of benzene is D ,. The symmetry elements common to both point groups Cj, and are E, Cj, and o,(x,z) = o which is the plane through...
