Fluoroalkyl silanes
View Patent ↗The present invention is directed to a fluorosilane represented by (L) 3 -Si—(CH 2 ) n —N(-Q 3 -R f )-Q 1 -R f where each n is independently an integer from 1 to 12; L is independently chosen from a hydrolysable or non-hydrolysable monovalent group R f is chosen from a C 2 -C 12 perfluoroalkyl provided that: i) one fluorine atom of the perfluoroalkyl can be optionally replaced by hydrogen, and/or ii) the perfluoroalkyl can be optionally interrupted by at least one oxygen, methylene, or ethylene; Q 1 is chosen from the group consisting of a C 2 -C 12 hydrocarbylene optionally interrupted by at least one divalent organic group; X 1 is chosen from O or S; and b) Q 1 and Q 3 are independently chosen from the group consisting of a C 2 -C 12 hydrocarbylene interrupted by at least one of —C(O)—O— or —O—C(O)—, and optionally further interrupted by at least one divalent organic group.
1. A fluorosilane represented by
wherein:
each n is independently an integer from 1 to 12;
wherein a=1, x=0; and l=0;
L is independently chosen from a hydrolysable or non-hydrolysable monovalent group
R f is chosen from a C 2 -C 12 perfluoroalkyl;
Q 1 is chosen from the group consisting of a C 2 -C 12 hydrocarbylene optionally interrupted by at least one divalent organic group;
X 1 is chosen from O or S;
a) Z 1 is —N[-Q 3 -(R f )]—; and
b) Q 1 and Q 3 are independently chosen from the group consisting of a C 2 -C 12 hydrocarbylene interrupted by at least one of —C(O)—O— or —O—C(O)—, and further interrupted by at least one divalent organic group.
2. The fluorosilane of claim 1 being a tertiary amine fluorosilane wherein:
a=1, x=0; and l=0; and
Z 1 is —N[-Q 3 -(R f )]-;
said tertiary amine represented by the formula:
Q 1 and Q 3 are independently chosen from the group consisting of a C 2 -C 12 hydrocarbylene interrupted by at least one —C(O)—O— and optionally further interrupted by at least one divalent moiety chosen from the group consisting of —S—, —S(O)—, —S(O) 2 —, —N(R 1 )—C(O)—, —C(O)—N(R 1 )—, —(R 1 )N—S(O) 2 —, and
3. A fluorosilane represented by
wherein:

L is independently chosen from a hydrolysable or non-hydrolysable monovalent group;
R f is chosen from a C 2 -C 12 perfluoroalkyl provided that: i) one fluorine atom of the perfluoroalkyl can be replaced by hydrogen, and/or ii) the perfluoroalkyl can be interrupted by at least one oxygen, methylene, or ethylene;
Q 1 is chosen from the group consisting of a C 2 -C 12 hydrocarbylene optionally interrupted by at least one divalent organic group;
X 1 is chosen from O or S;
a) Z 1 is —N[-Q 3 -(R f )]—; and
b) Q 1 and Q 3 are independently chosen from the group consisting of a C 2 -C 12 hydrocarbylene interrupted by at least one of —C(O)—O— or —O—C(O)—, and optionally further interrupted by at least one divalent organic group.
4. The fluorosilane of claim 1 being a tertiary amine fluorosilane wherein:
