Did you know?
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(CH3)3], which is in turn bonded to the rest of a molecule. This structural group is characterized by chemical inertness and a large molecular … See more Related to trimethylsilyl groups are "super" silyl groups of which there exist two varieties: A silicon group connected to three trimethylsilyl groups makes a tri(trimethylsilyl)silyl group (TTMSS or TMS3Si) and a … See more • Trimethylsilanol • Trimethylsilylacetylene • Trimethylsilyl chloride See more • Identification of Silylation Artifacts in Derivatization Reactions for Gas Chromatography See more In organic synthesis, TMS group is used as a protecting group for alcohols.

WebThe complex formation of Cucurbit[6]uril with DABCO and DABCO derivatives in solution has been studied using calorimetric titrations. For a better understanding of factors influencing the complex formation, several DABCO derivatives have been synthesized. All compounds have been characterized. Inclusion complex formation could not be observed. WebTrimethylsilyl (TMS) protecting group has been found to be very useful for the simultaneous protection of both the glycosyl donor- and the acceptor-substrates in oligosaccharide synthesis. Thus, while the per-O-trimethylsilylated glycosyl iodides served as the glycosyl donor, those bearing selectively exposed primary hydroxyl groups were found suitable as …
