WebTellurides also describe a class of organotellurium compounds formally derived from Te 2−. An illustrative member is dimethyl telluride, which results from the methylation of telluride salts: Dimethyl telluride is formed by the body when tellurium is ingested. Such compounds are often called telluroethers because they are structurally related ...
