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.
Claims3
A method of making a fluorosilicon nitrile compound comprising reacting a chlorosilicon nitrile compound with a fluorinating agent selected from the group consisting of HF, MF, MHF2 where M is Na, K, Rb, Cs or NH4, SbF3, ZnF2, PbF2, Hg2F2, AgF2, CoF2, CuF2, WF6, NaBF4, mixtures of NaF and H2SO4, BF3, BF3 etherates, Na2SiF6, NaPF6, NaSbF6, NaBF4, Me3SnF, PF5, PhCBF4, NOBF4, NO2BF4, KHF2, NH4HF2 under conditions effective to exchange fluorine atoms for the chlorine atoms in the chlorosilicon nitrile compound and wherein the chlorosilicon nitrile compound has a total of four substituents attached to a silicon atom, wherein one or two of the substituents are chlorine atoms, one or two of the substituents are cyanoalkyl groups, which may be 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.
