Anisoles 4 react with AlCl 3 and PCl 3 to yield the new fused bicyclic system derivatives 5 and 6 as major products in a one‐pot procedure. An alternative multi‐step synthesis of this system is also reported in which bis( o ‐methoxyaryl)phosphane oxides 11 are treated with AlCl 3 and PCl 3 ; the diarylphosphane oxides 11 are obtained by a new simple method.
