Analysis Note

Assay (iodometric): ≥ 98.0 %

Application

Selenium dioxide (SeO2) is mainly used to oxidize the activated carbon-bearing positions (α-methylene carbon atoms), particularly at allylic or propargylic sites. The more substituted end of the double bond undergoes oxidation. It can also be used as an oxidizing reagent to synthesize: Amides by oxidative amidation of aldehydes with amines. Tropone from cycloheptatriene in the presence of potassium dihydrogen phosphate.Acetyltetrahydrobenzofurans by oxidation of conjugated dienones. 9-hydroxy-undec-10-ynoate from methyl undec-10-ynoate.
