    01.08.2021 ? Back in the 1930s, Shipley et al. conducted AC electrolysis of several
    organic compounds, including fatty acids and their salts (e.g. potassium acetate,
    potassium propionate, and potassium butyrate), alcohols, aromatic hydrocarbons (e.g.
    benzene, p-xylene, aniline, hydroquinone), thiourea, thiosulphate, acetone,
    thiocyanate, ...

    01.08.2021 ? Electrochemical organic synthesis has recently attracted much attention
    because of its unique reactivity and environmentally benign approach. Conventional
    electrosynthesis uses either constant current or constant potential, known as direct
    current electrolysis. However, recently, alternating current electrolysis has begun
    receiving more attention.

    What is alternating current (AC) electrolysis?
    Under the constant voltage or current conditions, the electric current only flows in
    one direction, known as direct current (DC) electrolysis. Much less attention has
    been paid to alternating current (AC) electrolysis, where the flow of charge changes
    its direction periodically.

    What is direct current (DC) electrolysis?
    Nearly all synthetic organic electrochemical methods use a constant voltage or
    current to drive chemical transformations [ 2, 3, 4 ]. Under the constant voltage or
    current conditions, the electric current only flows in one direction, known as direct
    current (DC) electrolysis.

    What is organic electrosynthesis?
    Organic electrosynthesis: Electrosynthesis is naturally a huge topic within the field
    of electrochemistry. Although it has an extensive history, it has recently seen a new
    era of growth and is now largely considered its own field rather than simply a
    subdiscipline.
