Abstract

Diaryl ethers are useful intermediates in organic synthesis1 and are found in a large number of biologically active compounds. 2 The Ullmann ether synthesis3 has been extensively used for the formation of diaryl ethers. 4, 5 However, the harsh reaction conditions (125-220 C in neat phenol or solvents such as pyridine, collidine, or DMF), the usual requirement for stoichiometric (or greater) quantities of the copper complex, and the fact that unactivated ...
