Sodium selenite is a common source of selenium in the synthesis of zinc selenide (ZnSe). It is used as a key precursor in the synthesis of bismuth selenide nanocomposites, nickel cobalt selenides, selenium nanobelts and t-selenium nanotubes.
Sodium selenite can be used:
  • In dehydrogenation of benzoins to benzils and, flavanones to flavones under thermal and microwave conditions.
  • As a catalyst along with cysteine or glutathione in the reductive debromination of vic-dibromides to alkenes.
  • To prepare bis(methylmercuric) selenide (BMS) by reacting with methylmercuric chloride and reduced glutathione or cysteine.
