ABSTRACT:
The invention relates to a process for the electrosynthesis of alcohols and epoxy compounds by electrochemical reduction of organic halides in the presence of carbonyl derivatives in an organic solvent medium containing a supporting electrolyte. The organic halides contain an atom or a functional group which stabilizes carbon-ions, preferably fixed to the carbon carrying the halogen. The anode is made of a reducing metal preferably chosen from the group consisting of magnesium, aluminium, zinc, iron and their alloys. This process has the advantage of being simple, readily convertible to an industrial scale, especially as a result of the possibility of using a single-compartment cell and low-toxicity solvents. It can be applied to the electrosynthesis of numerous alcohols.
