For synthesis of some symmetrical selenide like dimethyl benzyl selenide, dicyclohexyl selenide and symmetrical diselenide like di-n- butyl diselenide, di1,1 ethylidene diselenide. under nitrogen atmosphere, a simple procedure has been developed by reaction of aryl or alkyl halide, element selenium (1equiv) and sodium borohydride react readily in water or ethanol to give either sodium hydrogen selenide or sodium selenide These sodium hydrogen selenide and sodium diselenide solution can be used as nucleophilic displacement reaction to formed different type of organoselenium product in high yields after which undergoes NMR, I.R, and Elemental analysis.
Symmetrical selenide, Diselenide, Aryl or alkyl halide, Elemental selenium
