Preparation of Cyclic Peroxides

For the preparation of cyclic peroxides from less electron-rich substrates, addition of some metal salts (MX) with non-nucleophilic anions that can support solvolysis, is beneficial (equation 8). 

Oxymercuration. A further extension of the peroxymercuration reaction is the preparation of cyclic peroxides in high yields from the appropriate diene (Scheme 29). Oxymercuration of penta-1,3-diene with mercury(ii) nitrate gives a mixture of 1,2- and 1,4-adducts which can be separated by chromatography. This is the...
