The Uses of Potassium peroxymonosulfate

To a solution of the SM (1.3 g, 7 mmol) in MeOH (150 mL) was added a solution of oxone (12 g) in H2O (150 mL). The reaction mixture was stirred at RT for 8 h. The mixture was concentrated to a reduced volume and the resulting aq mixture was extracted with DCM. The org layer was separated, dried (MgSO4), and concentrated in vacuo to provide the crude product that was used in the next step without further purification. [1.5 g, crude]

The Uses of Potassium peroxymonosulfate

Oxone is used for halogenation of a,b-unsaturated carbonyl compounds and catalytic generation of hypervalent iodine reagents for alcohol oxidation. It is a used for rapid, and good synthesis of oxaziridines.

General Description

OXONE^?, monopersulfate compound is a potassium triple salt mainly used as a stable, easy to handle and nontoxic oxidant.

Flammability and Explosibility

Non flammable

Purification Methods

This is a stable form of Caro's acid and should contain >4.7% of active oxygen. It can be used in EtOH/H2O and EtOH/AcOH/H2O solutions. If active oxygen is too low. it is best to prepare it afresh from 1mole of KHSO5, 0.5mole of KHSO4 and 0.5mole of K2SO4. [Kennedy & Stock J Org Chem 25 1901 1960, Stephenson US Patent 2,802,722 1957.] A rapid preparation of Caro's acid is made by stirring finely powdered potassium persulfate (M 270.3) into ice-cold conc H2SO4 (7mL) and when homogeneous add ice (40-50g). It is stable for several days if kept cold. Keep away from organic matter as it is a STRONG OXIDANT. A detailed preparation of Caro's acid (hypersulfuric acid, H2SO5) in crystalline form m ~45o from H2O2 and chlorosulfonic acid was described by Fehér in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 388 1963.
