Application

Selenium dioxide (SeO₂) is mainly used to oxidize the α-methylene carbon atoms adjacent to a double bond to form allylic hydroxy derivatives.Other applications:SeO₂ reacts with olefins in the presence of tert-butyl hydrogen peroxide to form allylic alcohols without the formation of rearrangement or dehydration by-products. This reagent system is also useful for the oxidation reactions of acetylenic fatty esters.SeO₂ can be used for the oxidation of 1,3,5-cycloheptatriene to form tropone.Piperidoindole systems on oxidation with SeO₂ forms either 2-acyl- or 3-acyl-indoles or fully aromatic β-carbolines, depending on the starting material.SeO₂ reacts with chlorotrimethylsilane to form selenium oxychloride in situ, which is an effective chlorinating reagent for alcohols. This reagent is a better alternative to thionyl chloride and other chlorinating agents.
