Selenocarbonyl compounds

General structure of a selenocarbonyl compound (selenocarbonyl group shown in blue ):

Selenoketone: A, B = org.

Selenoaldehyde remainder : A = H , B = org. Residual

Selenoamid: A = NH ₂ , NHR, NR ¹ R ² , B = organic radical

selenourea : A = NH ₂ , NHR, NR ¹ R ² , B = NH ₂ , NHR ³ , NR ³ R ⁴

Selenocarbonyl compounds are carbonyl compounds in which the oxygen atom of a carbonyl group has been replaced by a selenium atom. Selenoaldehydes are the selenium analogues of aldehydes and selenoketones are the selenium analogues of ketones . Selenoamides are the selenium analogues of amides , selenoureas are selenium analogues of ureas .

synthesis

Carbonyl compounds are converted to selenocarbonyl compounds by reaction with Woollins' reagent . Alternatively, hydrogen selenide or P ₄ Se ₁₀ can also be used to introduce selenium.
