Tellurol Tellurols are analogues of alcohols and phenols where tellurium replaces oxygen.〔Igor D Sadekov and A V Zakharov 1999 "Stable tellurols and their metal derivatives" Russ. Chem. Rev. 1999, vol. 68, 909.〕 Tellurols, selenols, and thiols have similar properties, but tellurols are the least stable.〔Brahim Khater, Jean-Claude Guillemin, Gábor Bajor, Tamás Veszprémi "Functionalized Tellurols: Synthesis, Spectroscopic Characterization by Photoelectron Spectroscopy, and Quantum Chemical Study" Inorganic Chemistry 2008 volume 47, p. 1502-1511. 〕 Although they are fundamental representatives of organotellurium compounds, tellurols are lightly studied because of their instability. Tellurol derivatives include telluroesters (RC(O)TeR') and tellurocyanates (RTeCN). ==Properties== Alkyltellurols are yellow liquids with a strong odors. Aryltellurols form colorless crystals. More stable than these compounds are the organoelement tellurols. These fairly stable compounds have the formulae (Me3Si)3CTeH, (Me3Si)3SiTeH, and (Me3Si)3GeTeH.
