These reactivity trends show clearly that polar effects are involved in these radical substitution reactions. The transition state is thought to involve a charge-transfer process from the radical (electron donor) to the pyridinium ion (electron acceptor) [114]. In this respect, frontier molecular orbital (FMO) theory [115] has been applied to explain the reactivity differences that have been observed upon varying the substituents at the pyridinium ion and upon altering the nucleophihc-ity of the attacking radical. FMO can also be used to explain the regioselectivities obtained in these homolytic aromatic substitutions. Here, the LUMO of the substituted pyridinium cation has the highest coefficients at carbon atoms 2 and 4... [Pg.492]
