Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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, MHF 2 where M is Na, K, Rb, Cs or NH 4 , SbF 3 , ZnF 2 , PbF 2 , Hg 2 F 2 , AgF 2 , CoF 2 , CuF 2 , WF 6 , NaBF 4 , mixtures of NaF and H 2 SO 4 , BF 3 , BF 3 etherates, Na 2 SiF 6 , NaPF 6 , NaSbF 6 , NaBF 4 , Me 3 SnF, PF 5 , PhCBF 4 , NOBF 4 , NO 2 BF 4 , KHF 2 , NH 4 HF 2 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. 2. The method of claim 1 , wherein the chlorosilicon nitrile compound is prepared by hydrosilylation of an alkene with a chloroalkylsilane. 3. The method of claim 2 , wherein the alkene is a cyanoalkene.
