Carboxylic acids are employed as the vital starting materials in organic synthesis. Various aromatic and aliphatic carboxylic participate electrochemical decarboxylative transformations which CO2 gets liberated generate active carbocation species that reacted with various nucleophiles to produce C−C, C−N, C−O, C−S, C−halogen bonds. L. Tian, Y. Wang et al. discuss recent developments decarboxyla...
