When a ketone 1 is treated with hydrogen peroxyde or a peracid, a formal insertion of oxygen can take place to yield a carboxylic ester 2. This process is called the Baeyer-Villiger oxidation ... 

Hydro-peroxyd, n. hydrogen peroxide, -per-sulfid, n. hydrogen persulfide, hydro-phil, n. hydrophile, hydrophil(ie). -phob, a. hydrophobe, hydrophobie.

The fluorine titration of chromium oxide was carried out at the Elf-Atochem Research Center, Pieire-Benite.The catalyst mineralization was carried out in a Parr bomb by reaction with sodium peroxyde. Fluorine ions were then titrated by a potentiometric method with a specific fluoride electrode. 

With hydrogen peroxide it is thought to form very unstable peroxydates. 

Moist potassium peroxodisulphate was accidentally exposed to traces of potassium hydroxide. It combusted spontaneously, causing the installations to catch fire. It is impossible to put out a fire involving this peroxydic compound with carbon dioxide or extinguishing powders although these agents are suitable for fires of chemical substances. Only water, which is usually not recommended in this case, can put out this type of fire. 

After storing sodium in m-xylene for 16 years, a layer of white soiid was found at the bottom of the container which detonated when the flask was moved. It seems that the reaction was due to a peroxydic impurity. After this accident, it...

Ion-radicals O2 generated on the surface interact fairly actively with molecules of various solvents. Peroxydes, hydroperoxydes, and other compounds may be produced as a result of such reaction. Due to low concentration of oxygen dissolved in the course of the experiment, small area of the film surface as well as low degree of occupation by charged molecules of chemisorbed oxygen (- 10 - 10 [55]) the accumulation rate of above products is low enough in this particular case. 

It is known that lifetime of solvated peroxyde ion-radicals vary in different solvents. Thus, it amounts to hours in pyridine and dimethyl-sulphoxide but falls far short of a minute in proton solvents like water or alcohols [56, 57]. 

Die Reaktion wird durch Peroxyde katalytisch beschleunigt (88) und ist analog der Reaktion der Olefine mit halogenierten Silancn zu Alkyl-silanen.

In addition to these extensive studies on electrophile-mediated intramolecular peroxydation of electron-rich C=C bonds, some examples of intramolecular hydroperoxide addition to electron-poor C=C bonds have been described. For example, several racemic analogues 371 of the naturally occurring plakinic acid were readily obtained by peroxymercuration followed by hydridodemercuration of the dienic acids 370 (Scheme 95 f °.
