Tris(trimethylsilyl)methane is the

organosilicon compound Organosilicon compounds are organometallic compounds containing carbon–silicon bonds. Organosilicon chemistry is the corresponding science of their preparation and properties. Most organosilicon compounds are similar to the ordinary organic c ...

with the formula (tms)₃CH (where tms = (CH₃)₃Si). It is a colorless liquid that is highly soluble in hydrocarbon solvents. Reaction of tris(trimethylsilyl)methane with methyl lithium gives tris(trimethylsilyl)methyllithium, called trisyllithium. Trisyllithium is useful in Petersen olefination reactions: :(tms)₃CH + CH₃Li → (tms)₃CLi + CH₄ :(tms)₃CLi + R₂CO → (tms)₂C=CR₂ + tmsOLi Trisyllithium is also an effective precursor to bulky

ligand In coordination chemistry, a ligand is an ion or molecule ( functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's elec ...

s. Some tris(trimethylsilyl)methyl derivatives are far more stable than less substituted derivatives. for example is a well-behaved

tellurol Tellurols are analogues of alcohols and phenols where tellurium replaces oxygen. Tellurols, selenols, and thiols have similar properties, but tellurols are the least stable. Although they are fundamental representatives of organotellurium compound ...
