Methanetellurol

Methanetellurol is the organotellurium compound with the formula 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.
