Transition metal peroxides handling

In the absence of a catalyst, the disproportionation is too slow to be observed at room temperature. Rapid, exothermic, and potentially explosive decomposition of hydrogen peroxide is initiated, however, by heat and by a broad range of catalysts, including transition metal ions, certain anions (such as I-), metal surfaces, blood (Figure 14.9), and even tiny particles of dust. Because decomposition is accelerated by light, hydrogen peroxide is stored in dark bottles. It is best handled in dilute aqueous solutions concentrated solutions and the pure liquid are extremely hazardous materials. 

Hg [212], is prepared from tert-butyl hydrogen sulfate and 27% hydrogen peroxide [212] and is commercially available as a 70 or 90% solution containing water and tert-butyl alcohol. Anhydrous rert-butyl hydroperoxide is obtained from the 70% aqueous solution by azeotropic distillation with toluene [213]. Anhydrous, as well as highly concentrated, tert-bvXy hydroperoxide must be handled with utmost care, because it may decompose violently in the presence of strong acids and some transition metals, especially manganese, iron, and cobalt [213, 214],... 

Tertiary alkylhydroperoxides are used most often as oxidizing agents with alkenes since primary or secondary alkylhydroperoxides are susceptible to rearrangement and decomposition. Alkylhydroperoxides are relatively soluble in organic solvents, are more stable, and are easier to handle than hydrogen peroxide.256 Both TBHP and cumyl hydroperoxide are commercially available and widely used. As with hydrogen peroxide, reaction of alkenes with hydroperoxides usually requires transition metal catalysts in order to form...
