Diphenyl selenide is an organoselenium compound with the formula (C₆H₅)₂Se. A pale yellow viscous liquid, it is a member of the series diphenyl ether, diphenyl sulfide, and diphenyl telluride. It can be prepared by treating phenyldiazonium chloride with sodium polyselenide.^[1]

Selected reactions

It can be oxidized with aqua regia to give diphenyl selenium dichloride.^[2] When oxidized with hydrogen peroxide, diphenylselenoxide results.
