employing potassium persulfate as an oxidant at room temperature has been disclosed. The protocol tolerated a variety of primary, secondary, and tertiary alcohol nucleophiles, affording corresponding benzyl ethers up to 80 % yields. This method shows good site selectivity and broad functional group tolerance. Mechanistic study indicates this strategy undergoes a single electron transfer process.
