Intramolecular cationic cyclization of β-hydroxyalkylphosphine oxides in the presence of an acid lead to the formation of fused bicyclic compounds with an incorporated phosphorus atom. Depending on the structure of the starting compound the formation of either phosphaindane or benzophosphorinane oxides has been observed. The key difference in the reactivity arises from the substitution pattern at the
