We have developed a new strategy for the generation of phosphenium dication equivalents from readily available phosphinic acids and Tf2O. The in situ-generated dication equivalents can be readily coupled with simple (hetero)biaryls to form the corresponding dibenzophospholes directly. This protocol can also be applied to the concise synthesis of six- A nd seven-membered phosphacycles as well as the largely ?-extended heteroacene derivatives, which are of great interest in the field of organic functional materials.

Intramolecular radical cyclization of phosphine oxides (R1R 2P(O)H) induced by radical generators affords the corresponding dibenzophosphole oxides in excellent yields. By applying this method, linearly π-extended ladder-type dibenzo
