Anodic syntheses. Part XVI. Oxidation of phenylenediacetic acids and benzylic ethers

Abstract
Electrolysis of o-, m-, and p-phenylenediacetic acids gives the diethers C6H4(CH2OMe)2 and the aldehydes CHO·C6H4·CH2·OMe, the latter resulting from anodic oxidation of the diethers. The ortho-diacid also affords a lactone. The anodic oxidation of ethers of this type to the corresponding aldehydes has been shown to be a general reaction of benzylic ethers having an electron-releasing substituent attached to the ring.
