| Abstract: | In Bergman cyclization the antisymmetric combination (n1-n2) of the hybrid orbitals at the radical sites in 1,4-dehydrobenzene is preferentially stabilized via through-bond interactions. The resultant splitting between the frontier orbitals is crucial in making Bergman cyclization a thermally symmetry allowed process. 1,4-Pentadiyne and 1,6-heptadiyne have been used as model systems to explore theoretically the role of orbital symmetry in Bergman cyclization. |
