Abstract
The microwave‐assisted synthesis of diaryl ethers directly from aryl halides and arylmethanesulfonates, which as latent phenols obviate a deprotection step prior to the SNAr reaction, in the presence of Cs2CO3 is described. The reaction time was very short (6–9 min), and good to excellent yields (53–90%) with the wide substrate scope were achieved without any catalyst.
