Organic peroxides are peroxides that have one or more organic substitutions. These class of peroxides includes classical peroxides such as t-BuOOH, UHP, dialkylperoxides, dialkyldioxiranes and newly peroxides including gem-hydroxyhydroperoxy alkanes and gem-dihydroperoxides (scheme 1). Among these peroxides, recently, gem-dihydroperoxides that are stable peroxidic derivatives of ketones and aldehydes, due to high oxidizing power, solubility in organic solvents, safety and easy utility have been widely interested. These peroxides also have been remarkable compounds because of their relevance to peroxidic anti-malarial drugs.1 Also, these compounds are important intermediates in the synthesis of a number of classes of peroxides including tetraoxanes, silateraoxans, spirobisperoxyketals, bisperoxyketals, 1,2,4,5-tetraoxa cycloalkanes.2 Recently, gem-dihydroperoxides have also been employed as reagents for oxidation reactions such as epoxidation of α, β-unsaturated ketones, enantioselective oxidation of 2-substituted 1, 4-naphtoquinones, oxidation of sulfide and as suitable oxidants in other organic reactions.3 As importance of these compounds, we have been improved their synthesis by using some green, inexpensive, commercially available and effective catalyst.4 Also, we have been reported first time synthesis of trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxalane as an efficient, powerful and solid cyclic gem-dihydroperoxide and we used it in many oxidative organic reaction. In this work, we briefly have reviewed organic peroxides and noble peroxides including trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxalane and urea- 2,2-dihydroperoxypropane have been presented and described (scheme 2).
