Synthesis of annulated dioxins as electron-rich donors for cation radical salts

The synthesis of a series of new alkoxylated linearly annulated dioxins is described together with their cyclic voltammetric behavior and some preliminary result on their ability to form cation radical salts. Of these dioxins, seven (, , , , , , ) are the first representatives of entirely new heterocyclic systems. Dioxins , , and gave good quality cation radical salts upon electrocrystallization.
