Trifluoromethyltrimethylsilane (often called Ruppert's reagent or Ruppert-Prakash reagent) is a reagent used in organic chemistry for the introduction of the trifluoromethyl group. The compound was first prepared in 1984 in Ingo Ruppert's group at the University of Bonn and introduced into the vocabulary of organic chemistry by the group of Surya Prakash at the University of Southern California five years later.
SiSiB® PC9795 fluorosilane is a colorless clear liquid.
Color and Appearance
Colorless clear liquid
Upon treatment with a source of fluoride the compound forms an -ate complex that attacks aldehydes and ketones to form trifluoromethyl methanols and esters to form trifluoromethyl ketones. It is thus a substitute for trifluoromethyllithium, which, unlike higher perfluoroalkyllithium compounds, is not isolable since even at low temperature it rapidly decomposes to yield lithium fluoride and difluorocarbene.
SiSiB® PC9795 alkyl silanes are supplied in net weight 1Kg bottle, 5Kg/25Kg pail.
In the unopened original container SiSiB® PC9795 has a shelf life of one year in a dry and cool place.
