Oxidation of Secondary Methyl Ethers to Ketones [PDF]
The Journal of Organic Chemistry, 2017 We present a mild way of converting secondary methyl ethers into ketones using calcium hypochlorite in aqueous acetonitrile with acetic acid as activator. The reaction is compatible with various oxygen- and nitrogen-containing functional groups and afforded the corresponding ketones in up to 98% yield.
