Methanetellurol
Chemical compound
From Wikipedia, the free encyclopedia
Methanetellurol is the organotellurium compound with the formula CH4Te or CH3TeH. It is the simplest organotellurium compound that has been purified in bulk. It is classified as a tellurol. A colorless gas, it decomposes to Te and methane near room temperature. It is prepared by reduction of dimethyl ditelluride using Na/NH3 followed by protonation of the CH3Te−Na+ (sodium methanetellurolate) with sulfuric acid.[1] Few publications describe this compound as a consequence of its instability and paucity of applications.
