Sodium hydroselenide is an inorganic compound with the chemical formula Na Se H. It is a salt of hydrogen selenide. It consist of sodium cations Na+ and hydroselenide anions −SeH. Each unit consists of one sodium, one selenium, and one hydrogen atom. Sodium hydroselenide is a selenium analog of sodium hydroxide NaOH.
Sodium hydroselenide can be made by reducing selenium with sodium borohydride:
Alternatively it can be made from sodium ethoxide exposed to hydrogen selenide: [1]
Sodium hydroselenide is not made for storage, instead it is used immediately after production in a fume hood thanks to the appalling odour of hydrogen selenide.
Sodium hydroselenide dissolves in water or ethanol. In humid air sodium hydroselenide is changed to sodium polyselenide and elemental selenium. [1]
Sodium hydroselenide is slightly reducing. [1]
In organic synthesis, hydrogen sodium hydroselenide is a nucleophillic agent for insertion of selenium. [1]
