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.

A fluorosilicon nitrile compound 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;
- subject to the proviso that the fluorosilicon nitrile compound is not
- SiF2(CH3)(CH2CH2CH(CN)CH3);
- SiF2(CH3)(CH2CH2CH2CN);
- SiF2(CH3)(CH2CH(CH3)CH2CN);
- or SiF2[CH2CH(CH3)CH2CN]2.
A fluorosilicon nitrile compound of general formula Si(R1)(R2)(R3)(R4), wherein one or two of R1-R4 are fluorine atoms, one or two of R1-R4 are cyanoalkyl groups, which are the same as or different from each other where two cyanoalkyl groups are present, and the remaining R1-R4, if any, are alkyl groups;
- subject to the proviso that the fluorosilicon nitrile compound is not SiF2(CH3)(CH2CH2CH(CN)CH3);
- SiF2(CH3)(CH2CH2CH2CN);
- SiF2(CH3)(CH2CH(CH3)CH2CN);
- or SiF2[CH2CH(CH3)CH2CN]2.
