text: Many industrial peroxides are produced using hydrogen peroxide. Reactions with aldehydes and ketones yield a series of compounds depending on conditions. Specific reactions include addition of hydrogen peroxide across the C=O double bond:
  In some cases, these hydroperoxides convert to give cyclic diperoxides:
  Addition of this initial adduct to a second equivalent of the carbonyl:
  Further replacement of alcohol groups:
  Triphenylmethanol reacts with hydrogen peroxide gives the unusually stable hydroperoxide, .
