organoselenium compound Organoselenium compounds (or seleno-organic) are chemical compounds containing carbon-to-selenium chemical bonds. Organoselenium chemistry is the corresponding science exploring their properties and reactivity. Selenium belongs with oxygen and sulf ...

with the formula (CH₃)₂Se. This colorless, malodorous, liquid is the simplest selenoether. It occurs in trace amounts in anaerobic environments. Dimethyl selenide is prepared by treating Se^2- sources with electrophilic methylating agents such as

methyl iodide Iodomethane, also called methyl iodide, and commonly abbreviated "MeI", is the chemical compound with the formula CH3I. It is a dense, colorless, volatile liquid. In terms of chemical structure, it is related to methane by replacement of one h ...
