ELECTROSYNTHESIS USING SACRIFICIAL ANODE - WHICH CONTRIBUTION TO THE ORGANIC-CHEMISTRY OF SILICIUM

The sacrificial anode electrochemical technique, using an undivided ce ll and a constant current density. provides a nice preparative route f or creating Si-Si and C-Si bonds without using alkali metals. Compared to the chemical organometallic synthesis. this method is extremely se lective and can lead to original compounds not accessible by the chemi cal routes. Bases, such as the 2-pyrrolidone magnesium salt electrogen erated in the same conditions, allowed the stereoselective synthesis o f Z-silyl enol ethers. Finally, the reduction potentials of a large nu mber of chorosilanes measured by cyclic voltammetry in standard condit ions are reported.
