Electrosynthesis using sacrificial anode: Which contribution to the organic chemistry of silicium

The sacrificial anode electrochemical technique, using an undivided cell and a constant current density. provides a nice preparative route for creating Si-Si and C-Si bonds without using alkali metals. Compared to the chemical organometallic synthesis. this method is extremely selective and can lead to original compounds not accessible by the chemical routes. Bases, such as the 2-pyrrolidone magnesium salt electrogenerated in the same conditions, allowed the stereoselective synthesis of Z-silyl enol ethers. Finally, the reduction potentials of a large number of chorosilanes measured by cyclic voltammetry in standard conditions are reported.
