Abstract

The combination of electrocatalysis and nickel catalysis achieves a decarboxylative cross-coupling of four types of α-oxocarboxylic acids and their derivatives with aryl trimethylammonium salts under mild conditions. This strategy enables a practical synthesis of aryl ketones, amides, esters, and aldehydes.
