Abstract

Compounds having the formula (F-I) below are provided herein:

wherein R 1 and R 2 at each occurrence are independently a C 1 -C 5000 alkyl group; R 3 at each occurrence is independently hydrogen or a C 1 -C 5000 alkyl group; R 4 is a C 1 -C 50 alkyl group or an unsubstituted or substituted phenyl group; R 5 at each occurrence is independently hydrogen or a C 1 -C 30 alkyl group; n is 1, 2, 3, or 4; and m+n is 5. Processes for preparing compounds of formula (F-I) as well as base stock and lubricant compositions containing compounds of formula (F-I) are also provided.

First claim

What is claimed is:

1. A compound having the following formula (F-I):

wherein:
R 1 is a C 6 -C 5000 alkyl group;
R 2 is a C 4 -C 5000 alkyl group;
R 3 at each occurrence is independently hydrogen or a C 1 -C 500 alkyl group;
R 4 is a C 1 -C 50 alkyl group or an unsubstituted or substituted phenyl group;
R 5 is hydrogen or a C 1 -C 30 alkyl group;
n is 1, 2, 3, or 4; and
m+n is 5.

2. The compound of claim 1 , wherein n is 1.

3. The compound of claim 1 , wherein a R 3 is hydrogen.

4. The compound of claim 1 , wherein a R 3 is a C 1 -C 100 alkyl group.

5. The compound of claim 1 , wherein R 1 is a C 6 -C 500 alkyl group and R 2 is a C 4 -C 500 alkyl group.

6. The compound of claim 1 , wherein:
an R 1 is a C 6 -C 30 linear alkyl group; and
an R 2 is a linear or a branched C 4 -C 5000 alkyl group.

7. The compound of claim 1 , wherein:
an R 1 or an R 2 is a branched C 1 -C 5000 alkyl group having the following formula (F-II):

wherein: R 6 and R 7 at each occurrence are each independently a hydrogen or a C 1 -C 30 linear alkyl group and k is a positive integer, provided however, among all of R 6 and R 7 , at least one is a C 1 -C 30 linear alkyl group and the sum of the carbon atoms of R 6 and R 7 is at least six carbon atoms for R 1 or at least four carbon atoms for R 2 ; and R 8 is a hydrogen or a C 1 -C 30 linear alkyl group.

8. The compound of claim 7 , wherein R 2 is a branched alkyl group represented by formula (F-II), and one of the following conditions is met:
(i) at least 50% of R 6 are hydrogen, and at least 50% of R 7 are independently a C 1 -C 30 linear alkyl groups; and
(ii) at least 50% of R 6 are independently C 1 -C 30 linear alkyl groups, and at least 50% of R 7 are hydrogen.

9. The compound of claim 7 , wherein k is from 50 to 500.

10. The compound of claim 7 , wherein k is from 2 to 50.

11. The compound of claim 1 , wherein R 1 and R 2 at each occurrence are the same or different and R 1 is a C 6 -C 100 linear alkyl and R 2 is a C 4 -C 500 linear alkyl.

12. The compound of claim 1 , wherein R 4 is a C 1 -C 50 linear alkyl group.

13. The compound of claim 1 , wherein R 5 is hydrogen.

14. The compound of claim 7 , having an isotacticity of at least about 60 mol %.
