Dimethylaminomethylphosphonic acid derivatives-promoted CuI-catalyzed synthesis of aryl ethers

Article abstract of DOI:10.1055/s-2006-941587

An inexpensive and efficient catalyst system for synthesis of aryl ethers has been developed by using 20 mol% CuI as the catalyst, 30 mol% dimethylaminomethylphosphonic acid derivatives as the new ligands, K ₂CO₃ as the base and toluene as the solvent. This is the first example using aminophosphonates as the ligands for Ullmann ether coupling reaction. Georg Thieme Verlag Stuttgart.
