Mild and metal-free conditions allow a fast and high-yielding synthesis of diaryl ethers - including bulky ortho-substituted diaryl ethers, which are difficult to obtain by metal-catalyzed protocols. Halo-substituents, racemization-prone amino acid derivatives, and heteroaromatics are also tolerated. The methodology is expected to be of high utility in the pharmaceutical industry.
