Anodic Cleavage of Carbon-Oxygen Bonds in Diaryl Ethers
Janissek, Paulo R.,Pardini, Vera L.,Viertler, Hans
, p. 576 - 577 (2007/10/02)
Diaryl ethers (1), which are model compounds for important linkages in lignins, are cleaved efficiently and conveniently by constant current anodic oxidation in methanol; the bis-acetals (2) are the main products (in 50-80 yield).
