Organic peroxides - Wikipedia

In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group (R−O−O−R′). If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article. The O−O bond of peroxides easily breaks, producing free radicals of the form RO (the dot … Zobacz więcej • Examples of organic peroxides • tert-Butyl hydroperoxide, a hydroperoxide (formula: ROOH) that is used to epoxide alkenes. • Dicumyl peroxide, a dialkyl peroxide (formula: ROOR) that is used to initiate polymerizations. Zobacz więcej Peroxides play important roles in biology. Many aspects of biodegradation or aging are attributed to the formation and decay of peroxides formed from oxygen in air. Countering these effects is an array of biological and artificial antioxidants. Hundreds of … Zobacz więcej Dialkyl peroxides, e.g., dicumyl peroxide, are synthesized by addition of hydrogen peroxide to alkenes or by O-alkylation of hydroperoxides. Diacyl … Zobacz więcej Several analytical methods are used for qualitative and quantitative determination of peroxides. A simple qualitative detection of peroxides is carried out with the iodine-starch reaction. Here peroxides, hydroperoxides or peracids oxidize the added Zobacz więcej The O−O bond length in peroxides is about 1.45 Å, and the R−O−O angles (R = H, C) are about 110° (water-like). Characteristically, the C−O−O−R (R = H, C) dihedral angles are about 120°. The O−O bond is relatively weak, with a bond dissociation energy Zobacz więcej In polymer chemistry Many peroxides are used as a radical initiators, e.g., to enable polymerization of acrylates.
