Abstract: Methods of synthesizing fluorosilanes containing cyano-substituted alkyl groups are provided. For example, 3-cyanopropyldimethylfluorosilane may be produced by reacting tetramethyldisiloxane and boron trifluoride to obtain fluorodimethylsilane and then reacting the fluorodimethylsilane with allyl cyanide, in the presence of a hydrosilylation catalyst.

Abstract: Novel fluorosilicon nitrile compounds, and methods of preparing them, are described. The fluorosilicon nitrile compounds are characterized by having a total of four substituents attached to a silicon atom, wherein one or two of the substituents are fluorine atoms, one or two of the substituents are cyanoalkyl groups, which are the same as or different from each other, and the remainder of the substituents, if any, are alkyl groups, which are the same as or different from each other.

Abstract: A method of making CF3CH2SH, comprising a step of reacting CF3CH2X, wherein X is halide or tosylate, with MSH, where M is an alkali metal such as Na or K, to yield CF3CH2SH. More specifically, a method of making CF3CH2SH, a step of reacting CF3CH2CI with a molar excess of NaSH in a reaction medium of one or more polar organic solvents at a temperature of from about 70 C to about 110 C for a time of from about 1 to about 5 hours.
