a Traditional methods for C4H6 synthesis include thermal cracking of petroleum and extractive distillation of C4 fractions, which recycle large quantities of organic solvents to separate products with close boiling points. b This work describes the development of an electrochemical method for synthesizing C4H6 that overcomes previous challenges by relying on petroleum and organic solvents, which favor the green and sustainable production of chemical products.
