TITLE

PERFLUOROPOLYVI YL MODIFIED A YL INTERMEDIATES AND

MONOMERS

FIELD OF THE INVENTION

The present invention comprises aryi compounds having partialiy f!uorinated tails which can be useful as intermediates and starting materials for producing various water and oil repellents, soil resists, and surfactants.

BACKGROUND OF THE INVENTION

Water and oil repellents, soil resists, and surfactants compounds generally are prepared from linear perfluorinated alcohols. These alcohols are expensive and are prepared through several step synthesis. These alcohols are either then reacted to make final products or further synthesized into intermediates prior to making final products. New starting materials are needed that do not utilize linear perfluorinated alcohols.

U.S. Patent 7,531 ,700 teaches fiuorinated solvents having benzene rings with a) perfluorinated pendent alkyl groups, b) alkyl, alkoxy, or oxyaikyl groups and c) optionally halogen pendent groups useful for the manufacture of organic electronic devices. These solvents are non- reactive.

Patent Application VVO 2007/149449 teaches fiuoroalkoxystyrenes prepared by contacting fiuorinated olefin with a solution of hydroxysiyrene. These fiuoroalkoxystyrenes are useful in resins, elastomers, polymers or coatings.

What is needed are nonlinear compounds as starting materials and intermediates to produce compounds for water and oil repellents, soil resists, and surfactants compounds. The present invention meets this need.

methyl 4-(1 , 1 ,2-trif!uoro-2-(1 ,1 ,2,3,3,3-hexafluoro-2- (perfluoropropoxy)propoxy)ethoxy)benzoate

In the dry box, THF (500mL) and methyl 4-hydroxybenzoate (28.8 g, 0.175 mo!) were added to an oven dry RB flask equipped with a stirrer, Potassium carbonate (12.00 g, 0.087 mo!) was then added. 1 ,1 ,1 ,2,2,3,3- Heptafluoro-3-(1 ,1 ,1 ,2,3,3-hexafluoro-3-(1 ,2,2trif!uorovinyioxy)propan-2- y!oxy)propane (94.5 g, 0.219 mo!) was then added via the addition funnel and the reaction allowed to stir at room temperature. The reaction mixture was heated to a gentle reflux, oi! temperature about 80°C, under nitrogen overnight. An aliquot was withdrawn and concentrated under vacuum and analyzed via proton NMR that showed the complete conversion to the desired materia!. The cooled reaction mixture was then filtered through silica gel and then concentrated at reduced pressure, resulting in 101 .52 g (99.33%) yield of the desired material. Example 12

Water (500.0 mL) and potassium hydroxide were added to a round bottom flask equipped with a stirrer. Methyl 4-(1 ,1 ,2-trifiuoro-2- (1 ,1 ,2,3,3,3-hexafluoro~2-(perfluoropropoxy)propoxy)ethoxy)benzo ate (50.0 g, 0.0858 mol), as prepared in Example 1 1 , was then added via the addition funnel and the reaction was placed in an oil bath and heated to a gentle reflux overnight. The flask was allowed to cool before acidifying with concentrated HCi, down to ph~1 .0. The precipitate was filtered and dried overnight. The solids were analyzed by proton NMR to be 4-(1 , 1 ,2- trif!uoro-2-(1 ,1 ,2,3,3,3-hexafiuoro-2-

(perfluoropropoxy)propoxy)ethoxy)benzoic acid (52.00 g, 0.0912 mol) as prepared in Example 12 and thionyl chloride (385 g, 3.09 mol) were place in an oven dried RB flask equipped with a stirrer, reflux condenser and under nitrogen. The reaction was placed in an oil bath and heated to a gentle reflux overnight. The content was analyzed by proton NMR and shown to be 4-(1 ,1 ,2-trifluoro-2-(1 , 1 ,2,3,3,3-hexafIuoro-2- (perfluoropropoxy)propoxy)ethoxy)benzoyi chloride.

in the dry box, tetrahydrofuan (50 mL) and diethanoi amine (0.714 g, 0.0068 mol) were added to a round bottom flask equipped with a stirrer, 4-(1 ,1 ,2-trifluoro-2-(1 ,1 ,2,3,3,3-hexafluoro-2-

(perfluoropropoxy)propoxy)ethoxy)benzoyl chloride (2.00 g, 0.0034 mol) as prepared in Example 13 was then added and the reaction was stirred for one hour. The content was analyzed by proton NMR and shown to be N,N-bis(2-hydroxyethyl)-4-(1 ,1 ,2-trifluoro-2-(1 ,1 ,2,3,3,3-hexafluoro-2- (perfluoropropoxy)propoxy)ethoxy)benzamide.

(perfluoropropoxy)propoxy)ethoxy)-4-vinyl benzene

In the dry box, THF (50mL) and 4-vinylphenoi (5.00 g of a 10% solution in propylene glycol) were added to an oven dry RB flask equipped with a stirrer, Potassium carbonate (0.35 g, 0.0025 mo!) was then added. 1 ,1 ,1 ,2,2,3,3-Heptafluoro-3-(1 ,1 ,1 ,2,3,3-hexafiuoro-3- (1 ,2,2thfluoroviny1oxy)propan-2-y1oxy)propane (2.70 g, 0.00825 mol) was then added via the addition funnel and the reaction allowed to stir at room temperature. The reaction mixture was heated to a gentle reflux under nitrogen overnight. An aliquot was withdrawn and concentrated under vacuum and analyzed via proton NMR which showed the complete conversion to be 1 -(1 ,1 ,2-trifluoro-2-(1 ,1 ,2,3,3,3~hexafluoro~2- (perfluoropropoxy)propoxy)ethoxy)-4-vinyibenzene. The cooled reaction mixture was then concentrated at reduced pressure taken up in methylene chloride washed with water (-25 mL) separated, then dried over anhydrous sodium sulfate. The separated organic phase was then concentrated at reduced pressure and then column chromatograph on silica gel obtaining 1 .15 g (about 50.0%) of the theoretical yield) of product.
