Selenium Dioxide → HCID 21291309, compound

Participants

Reaction Steps

A mixture of bathocuproine (0.8 g, 2.2 mmole), selenium dioxide (1.16 g, 10.4 mmole), dioxane (29.6 ml) and water (1.25 ml) was heated with stirring in an oil bath at 110° for 2 hr. The hot mixture was then filtered through Celite to remove selenium metal. Water was added to the hot filtrate until slight cloudiness appeared. The mixture was then placed in the refrigerator to allow the product to precipitate. The product, which was contaminated by red selenium metal, was collected by vacuum filtration. Yield=88%. Mp=165°-170°.
