Peroxymaleic acid can also be generated in situ from maleic anhydride and 30% H₂O₂ in NMP, and has been found to be a very effective oxidant for conversion of sulfides to sulfoxides. For a study of stoichiometric and catalytic oxidations with this system, see: J. Org. Chem., 61, 5693 (1996).
• Also undergoes photochemical and thermal (2+2)-cycloadditions with alkenes. For reaction with 1-alkynes, see: Chem. Ber., 102, 3974 (1969).
