title: Synthesis of π-extended dibenzophospholes by intramolecular radical cyclization and their properties.
abstract: Intramolecular radical cyclization of phosphine oxides (R(1)R(2)P(O)H) induced by radical generators affords the corresponding dibenzophosphole oxides in excellent yields. By applying this method, linearly π-extended ladder-type dibenzophosphole oxides were successfully synthesized.
