Research has been conducted on the alpha-(2)- and alpha-(4-methoxyphenoxy)alkanoic acids. The study of the anodic oxidation of these acids carried out in developing orthoquinone bis- and monoketals and in investigating electrochemically induced spirolactonization is presented.

Anodic oxidation of appropriately substituted 2-methoxyphenols or alpha-(2-methoxyphenoxy)-2-methylpropionic acids in the presence of methanol furnishes stable orthoquinone monoketals, and thus constitutes a valuable alternative to the use of chemical oxidants that are often based on toxic metallic species.

Electrochemical methods enable the conversion of the commercially available tetrachlorocyclopropene into hexakis(trimethylsilyl)-3, 3'-bicyclopropenyl. Analysis of the electrochemical reaction between tetrachlorocyclopropene and chlorotrimethylsilane reveals the occurrence of first two trimethylsilylations at the vinylic positions. The tris(trimethylsilyl)cyclopropenyl radical undergoes a radical coupling reaction after the incorporation of the third trimethylsilyl group, producing the bicyclic product.
