Abstract
A decarboxylation coupling electrocatalysis method for catalyzing an aromatic trimethyl ammonium salt and α-nickel ketonate is provided. The method includes the following steps: step 1, adding aryl-ammonium trifluoromethyl sulfonate, α-keto acid and sodium acetate in a molar ratio of 1:2:2 into a reaction bottle in a nitrogen atmosphere, adding an electrolyte n-BuNBF, and then adding a mixed solution of acetonitrile and N,N-dimethylformamide, where a volume ratio of the acetonitrile to the N,N-dimethylformamide is 1:4; and step 2, stirring a mixture in step 1 so as to dissolve the mixture, inserting two electrodes, using a graphite electrode as a positive electrode and a nickel electrode as a negative electrode, adding water for stirring after a reaction, and conducting extraction, drying and purification to obtain an aromatic ketone compound.
