Aryl methyl ethers are widely used as protecting groups for phenols and are important components of a large number of industrial products. They are conventionally prepared by O-methylation of phenols with dimethyl sulfate or iodomethane. Dimethyl carbonate has attracted attention as an environmentally friendly equivalent of these reagents, because it has low toxicity and the only byproducts of the reaction are methanol and carbon dioxide. Historically, many other reagents have been described for the preparation of aryl methyl ethers, as summarized elsewhere.[6] This review focuses on those with the widest applicability.
