DESCRIPTION
Application
Sodium selenite can be used:
In dehydrogenation of benzoins to benzils and, flavanones to flavones under thermal and microwave conditions.[1] As a catalyst along with cysteine or glutathione in the reductive debromination of vic-dibromides to alkenes.[2] To prepare bis(methylmercuric) selenide (BMS) by reacting with methylmercuric chloride and reduced glutathione or cysteine.[3]

Sodium selenite is a common source of selenium in the synthesis of zinc selenide (ZnSe).[4] It is used as a key precursor in the synthesis of bismuth selenide nanocomposites,[5] nickel cobalt selenides,[6] selenium nanobelts[7] and t-selenium nanotubes.[8]
