Dimethyl selenide is the organoselenium compound with the formula (CH3)2Se. This colorless, malodorous, liquid is the simplest selenoether. It occurs in trace amounts in anaerobic environments.[1]

Dimethyl selenide is prepared by treating Se2- sources with electrophilic methylating agents such as methyl iodide:

Na2Se + 2 CH3I → (CH3)2Se + 2 NaI
