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.
Claims7
