Sodium percarbonate allows the convenient preparation of peroxy acids from acid chlorides, and even from the acids themselves.
Anhydrous [2-percarboxyethyl] functionalized silica is an advantageous oxidant for epoxidation of olefins. The acidic silica surface does not catalyze ring-opening reactions except for particularly activated styrene oxide. Alkenes carrying hydroxyl groups react with silica-supported peracid faster than unsubstituted alkenes. Products can be isolated after simple filtration and solvent evaporation.

The oxidation of malononitrile derivatives with peracid in methanol proceeds with loss of the cyano groups to yield methyl esters in high yield. The method was applied to a variety of malononitrile derivatives, some of which were prepared by Pd- or Ir-catalyzed asymmetric allylic substitution.
