Abstract

Abstract 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.
