Abstract

A model acid, Ph 2(Me)SiCH 2COOH, undergoes two competing anodic reactions, decarboxylation and desilylation under non-Kolbe conditions (e.g., at a C anode, in MeOH). The effects of anode material, current density, substrate concentration and base concentration on the two competing reactions have been investigated. The scope of the reaction was extended to other α-silyacetic acids of type R 2R′SiCH 2COOH, in order to study the influence by the substituents attached to silicon on the nature and distribution of products emerged from electrolysis.
