Alkyl ether fragmentations of radical anions of several phenyl and nitrophenyl methyl ethers have been theoretically studied by means of the AM1 semiempirical method. The cleavage occurs through a π*-σ* intramolecular electron transfer process, that is made possible by the lengthening of the C-O alkyl ether bond. The C-O scission is slowed down by the introduction of substituents that increase the σ*-π* energy gap.
