SELENIUM DIOXIDE reacts with water, particularly hot water, to give selenious (selenous) acid, a weak acid that is corrosive. Stable to light and heat. Rapidly absorbs dry hydrogen fluoride, hydrogen chloride, hydrogen bromide to form the corresponding selenium oxohalide. A good oxidizing agent.
The oxygen-catalyzed reaction of trialkylboranes with 1 equiv of selenium dioxide affords a dialkyl selenide as the major product. 26 Similarly, dialkyl selenides have been prepared by reaction of alkyllithiums or Grignard reagents with selenium dioxide. 27. Related Reagents. Selenium(IV) Oxide-t-Butyl Hydroperoxide.
Selenium dioxide imparts a red colour to glass. It is used in small quantities to counteract the colour due to iron impurities and so to create (apparently) colourless glass. In larger quantities, it gives a deep ruby red colour. Selenium dioxide is the active ingredient in some cold-bluing solutions.
