Indirect electrochemical α-methoxylation of aliphatic ethers and acetals - reactivity and regioselectivity of the anodic oxidation using tris(2,4-dibromophenyl)amine as redox catalyst
technically important α-methoxylation of aliphaticethers and acetals to form mixed acetals respectively aldehydes or ortho-esters can be performed electrochemically at low potentials in methanol solution using an undivided cell and tris(2,4-dibromophenyl)amine as redox catalyst. The regioselectivity is usually considerably higher as compared with direct electrolysis in the absence of a catalyst. Especially
