Abstract

Organic substrates, such as cyclic ethers, N-substituted amides, ketones, alkyl-aromatic substances and alkyl-heteroaromatic substances can be anodically alkoxylated, especially methoxylated, in the presence of an alcohol. Alkoxylation in the presence of a mediator or in a divided cell using a solid electrolyte is known. The anodic alkoxylation according to the invention is carried out in the absence of a mediator in an undivided electrolytic cell using a diamond anode or gold anode and allows for high yields and a high current efficiency.
