Trimethylsilyldiazomethane is the organosilicon compound with the formula (CH 3) 3 SiCHN 2.It is classified as a diazo compound.Trimethylsilyldiazomethane is commercially available as solutions in hexanes, DCM, and ether.
Tetramethylsilane is the accepted internal standard for calibrating chemical shift for 1 H, 13 C and 29 Si NMR spectroscopy in organic solvents (where TMS is soluble). In water, where it is not soluble, sodium salts of DSS, 2,2-dimethyl-2-silapentane-5-sulfonate, are used instead.
A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry.This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3) 3], which is in turn bonded to the rest of a molecule.
Tris(trimethylsilyl)silane is the organosilicon compound with the formula (Me 3 Si) 3 SiH (where Me = CH 3).It is a colorless liquid that is classified as a hydrosilane since it contains an Si-H bond.
Trimethylsilylacetylene is used in Sonogashira couplings as the equivalent of acetylene.Using this protected alkyne, as opposed to acetylene itself, prevents further coupling reactions.
