Magnesium monoperoxyphthalate
Magnesium monoperoxyphthalate (MMPP) is a chemical compound used as an oxidizing agent in organic synthesis. It is a solid, white powder that is soluble in water and is commonly used in the laboratory for the oxidation of alcohols to aldehydes or ketones.
Chemical Structure[edit]
MMPP is a complex of magnesium ion and monoperoxyphthalate anion. The monoperoxyphthalate anion is a derivative of phthalic acid, where one of the carboxylic acid groups has been replaced by a peroxide group (-OOH).
Preparation[edit]
MMPP can be prepared by the reaction of hydrogen peroxide with phthalic anhydride in the presence of a magnesium salt, such as magnesium sulfate.
Uses[edit]
MMPP is a selective oxidizing agent. It is used in the laboratory for the oxidation of primary and secondary alcohols to aldehydes and ketones, respectively. It is also used for the oxidation of sulfides to sulfoxides and sulfones, and for the oxidation of amines to nitroso compounds.
Safety[edit]
MMPP is a strong oxidizing agent and can react violently with reducing agents. It should be handled with care, using appropriate safety equipment.
