A mild one-pot ozonolysis-oxidation process enables the synthesis of carboxylic acids from alkenes. Conducting the ozonolysis in an aqueous organic solvent eliminates secondary ozonide formation and the intermediates generated are readily converted into a carboxylic acid by adding sodium chlorite. The desired acids are isolated in high purity and high yield by simple extraction after a reductive quench.
