ABSTRACT:
Disclosed is a process for the electrochemical transformation of a compound to form a product, the process comprising (i) effecting the transformation in the presence of an electrolyte comprising at least one room temperature ionic liquid, wherein the ionic liquid is air-stable and moisture-stable, (ii) recovering the product, and optionally (iii) recovering the ionic liquid. The process can be used to effect the electrochemical transformation of a wide range of organic compounds.
