Since metal oxides contain a wide variety of surface sites behaving as Brønsted acids and bases, reactions constantly occur when the surface comes into contact with an aqueous solution. The water molecules dissociate into protons and hydroxyl groups which strongly bind to the oxygen and metal atom...
Effects of alcohols, phenols, acids, tertiary amines, sulfur-containing compounds, and other additives on the rate of oxirane group-amine reaction in solvents at 25掳C. were studied. Carboxylic acids which contain hydroxyls on the adjace... AM Partansky - Epoxy Resins 被引量: 14发表: 1970...
The reaction of α-metallated isocyanides with derivatives of dibasic acids, for example dimethyl oxalate, affords bioxazolyls (equation 119), and polyoxazolyls have been prepared from isonitriles and suitably substituted oxazoles, e.g. equation (120). (118) (119) (120) Another synthesis ...
Corrosion of metals is also associated with oxidation-reduction reactions and terminates upon complete oxidation of the metal. Many important biological phenomena, including respiration—the assimilation of carbon dioxide by plants with the subsequent liberation of oxygen—and metabolism, are associated with...

1.12.3.6.3.(iii) Oxidation of thiols to sulfenic acids The biological activity of thiols depends, to a large extent, on the facility with which the SH group is oxidized to high sulfur oxides (RSOxH) and disulfides (RSSR). Sulfenic acids (RSOH), transient intermediates in many organic and...
The reductive dissolution of metal oxides/hydroxides occurs in the following sequential steps (Stone, 1986, 1991): (1) diffusion of the reductant molecules to the oxide surface, (2) surface chemical reaction, and (3) the release of reaction products and diffusion away from the oxide surface....
