Diethyl selenide is an organoselenium compound with the formula C
₄H
₁₀Se. First reported in 1836, it was the first organoselenium compound to be discovered.[1][2] It is the selenium analogue of diethyl ether. It has a strong and unpleasant smell.

Occurrence

Diethyl selenide has been detected in biofuel produced from plantain peel.[3] It is also a minor air pollutant in some areas.

Preparation

It may be prepared by a substitution reaction similar to the Williamson ether synthesis: reaction of a metal selenide, such as sodium selenide, with two equivalents of ethyl iodide or similar reagent to supply the ethyl groups:
