General description

Chlorotrimethylsilane (TMSCl) is a silylating agent employed in the silylation of alcohols, amines, carboxylic acids, thiols, and other functional groups. Silyl group serves as a protecting group for these original functional groups.

Application

Chlorotrimethylsilane (TMSCl) can be used as a reagent:
  • To synthesize allenylsilane via carbolithiation of conjugated enynes with aryllithium.
  • In the reductive coupling of aldehydes and ketones to produce corresponding 1,2 diols in the presence of zirconocene dichloride and magnesium.
  • To prepare 4,4′-bis(trimethylsilyl)bicyclohexyl-2,2′-diene from 1,3-cyclohexadiene by reductive disilylation reaction.

Neanderthal dietary reconstructions have, to date, been based on indirect evidence and may underestimate the significance of plants as a food source. While zooarchaeological and stable isotope data have conveyed an image of Neanderthals as largely carnivorous, studies on dental

We have previously described the efficient guidance and unidirectional sliding of actin filaments along nanosized tracks with adsorbed heavy meromyosin (HMM; myosin II motor fragment). In those experiments, the tracks were functionalized with trimethylchlorosilane (TMCS) by chemical vapor deposition (CVD)

In the in vitro motility assay, actin filaments are propelled by surface-adsorbed myosin motors, or rather, myosin motor fragments such as heavy meromyosin (HMM). Recently, efforts have been made to develop actomyosin powered nanodevices on the basis of this assay
