The reactions of aryl halides with phenols promoted by CsOH/dimethyl sulfoxide (CsOH/DMSO) led to diaryl ethers. This method was free of transition metal catalysts and ligands, and could be performed without inert gas protection. Therefore, it was a concise and green synthetic method. Based on the experimental results, a mechanism involving the benzyne intermediates is supposed.

Key words: aryl halides, phenols, diaryl ethers, CsOH, dimethyl sulfoxide (DMSO), benzyne
