摘要： Disclosed is a method for synthesizing β-cyano ketone compound, including steps of (1) adding a α-keto acid and sodium hydroxide to a separator-free electrolytic cell, adding acetonitrile thereto, and dissolving the α-keto acid and sodium hydroxide in acetonitrile by stirring to be uniform, to obtain a dissolution solution; (2) adding an alkene or a derivative thereof, cyanobenziodoxolone, and an electrolyte to the dissolution solution, to obtain a mixed solution; (3) subjecting the mixed solution to an electrochemical reaction by electrifying a cathode of a platinum sheet, and an anode of a graphite electrode to obtain a reacted solution; and (4) after the electrochemical reaction, collecting the reacted solution, adding water thereto and stirring to obtain a mixture, subjecting the mixture to an extraction to obtain an organic phase, drying the organic phase and purifying, to obtain the β-cyano ketone compound.
