Various cyclenones have been homologated by a two-step sequence involving a reaction with α-selenoalkyl-lithium compounds and further reaction of the resulting β-hydroxyselenides with thallium(I) ethoxide in chloroform; an unusually high propensity of the alkyl groups to migrate in place of the vinyl moiety has been observed.
