Abstract

[2311-91-3] C8H6O5 (MW 182.14) InChI = 1S/C8H6O5/c9-7(10)5-3-1-2-4-6(5)8(11)13-12/h1-4,12H,(H,9,10) InChIKey = GLVYLTSKTCWWJR-UHFFFAOYSA-N (Mg salt·6H2O) [84665-66-7] C16H22MgO16 (MW 494.69) InChI = 1S/2C8H6O5.Mg.6H2O/c2*9-7(10)5-3-1-2-4-6(5)8(11)13-12;;;;;;;/h2*1-4,12H,(H,9,10);;6*1H2/q;;+2;;;;;;/p-2 InChIKey = WWOYCMCZTZTIGU-UHFFFAOYSA-L (mild peroxycarboxylic acids for effecting epoxidation of π-bonds, Baeyer–Villiger reactions, and the oxidation of diverse heteroatoms including nitrogen, sulfur, and selenium) Alternate Name: MPP. Physical Data: monoperoxyphthalic acid: mp 110–112 °C (dec).2 Solubility: monoperoxyphthalic acid: sol ether; magnesium monoperoxyphthalate: sol water, low molecular weight alcohols; very low sol organic solvents such as dichloromethane. Form Supplied in: magnesium monoperoxyphthalate: white crystalline powder; commercially available as the hexahydrate. Preparative Methods: monoperoxyphthalic acid is prepared as required by the addition of phthalic anhydride to 30% aqueous,Hydrogen Peroxide3a in the presence of Sodium Hydroxide3b or Sodium Carbonate.3c Magnesium monoperoxyphthalate is prepared by the addition of phthalic anhydride and Magnesium Oxide to aqueous hydrogen peroxide.3d Drying: magnesium monoperoxyphthalate should be dried over calcium chloride in a desiccator. Handling, Storage, and Precautions: magnesium monoperoxyphthalate may be stored at room temperature. All work should be carried in an efficient fume hood behind a polycarbonate safety screen.
